How do you identify equivalent expressions?

Equivalent Expressions Equivalent Expressions are expressions that have the same value. They may look different but will have the same result if calculated. For example, and are equivalent expressions. See why below: The two expressions have the same answer, 27. Therefore, we can say that they are equivalent expressions.

Which expressions are equivalent to?

Two mathematical expressions are equivalent if and only if they result in the same value for all matching values of the variables. Therefore, we can determine if two expressions are equivalent by plugging in many different matching values of the variables to make sure we get the same value out of each expression in every instance.

What is the meaning of equivalent expressions?

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable. To check whether a more complex expression is equivalent to a simpler expression:

How do you find the equivalent expression?

equivalent expressionshave the same value but are presented in a differentformat using the properties of numbers eg, ax + bx = (a + b)x are equivalent expressions. Strictly, they are not “equal”, hence we should use 3 parallel lines in the”equal” rather than 2 as shown here.

What is an example of an equivalent expression?

Examples of Equivalent Expressions 3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. 3x + 6 = 3 × 4 + 6 = 18. and can also be written as 6(x2 + 2y + 1) = 6×2 + 12y + 6. In this lesson, we learn to identify equivalent expressions.

What are equivalent expressions?

When two expressions are equivalent, what is the meaning of the expression?

If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable. Arrange the terms in the same order, usually -term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.

How do we rearrange formulas?

Formulas are equations that contain or more variables; they describe relationships and help us solve problems in geometry, physics , etc.

How to make an equation true for all values of a variable?

For the equation to be true for all values of the variable, the two expressions on each side of the equation must be equivalent. For example, if for all values of , then: must equal . must equal . Distribute any coefficients on each side of the equation.

How to distribute coefficients?

Distribute any coefficients: Combine any like terms on each side of the equation: -terms with -terms and constants with constants. Arrange the terms in the same order, usually -term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.

What happens if all the terms in two expressions are identical?

If all of the terms in the two expressions are identical, then the two expressions are equivalent.

How to isolate a variable?

To isolate a specific variable, perform the same operations on both sides of the equation until the variable is isolated. The new equation is equivalent to the original equation.

What is equivalent expression?

As the name suggests, equivalent expressions are algebraic expressions that, although they look different, turn out to really be the same. And since they’re the same, they will yield the same results no matter what numbers we substitute for their variables. Let’s consider this algebraic expression: 2 ( x ^2 + x ).

What is an algebraic expression?

An algebraic expression is a string of numbers, variables, mathematical operations, and possibly exponents. For example, 4 x + 3 is a basic algebraic expression. Or we could get a little more complex with 3 x (2 x ^2 + 2 x – 5) + 6 y. Notice that both of these examples contain the previously listed elements of an algebraic expression: numbers, variables, and mathematical operations, and the second expression contains the optional exponent.

Why are graphs exactly the same?

Well, since equivalent expressions produce identical solutions for all values, their graphs are exactly the same . If we wanted to, we could graph a hundred equivalent expressions, and the result would still be one line because all the expressions would produce the same solutions.

Why do two expressions have their own tracks?

In fact, if we graph the two expressions, we can see that they only intersect at that one point where they happen to yield identical solutions. However, they have their own tracks before and after that point because they’re not equivalent expressions. While we’re at it, let’s see what happens when we graph the following equivalent expressions:

What happens when you plug in matching values of the variables into two mathematical expressions?

If we plug in matching values of the variables into two mathematical expressions, and we get a different value out from each expression, then the two expressions are not equivalent.

What happens if you use the same number for x?

Because these two expressions are really the same, no matter what number we substitute for x, the results will always be identical. If we use 0, both expressions come out to 0. If we use 10, both expressions come out to 220. If we use 100, both expressions come out to 20,200. We get the same result no matter how large or small the number we use for x.

How to tell if an equation is a true number sentence?

An equation has one specific solution or set of solutions that will make the number sentence true. In this case, the equation is a true number sentence when x = 1. There is one specific solution. In an expression, however, since there’s no equal sign, variables are free to be variables.

Steps for Using the Distributive Property to Write Equivalent Expressions

Step 1: Given an expression of the form {eq}ax + b {/eq}, we must first list all of the factors of the coefficient {eq}a {/eq}.

Equations and Definitions for Using the Distributive Property to Write Equivalent Expressions

Distributive Property: The distributive property says that the sum of two addends multiplied by a value is equivalent to multiplying each of the addends by the value and then adding. Mathematically, this property is written as {eq}a (b+c) = ab + ac {/eq}.

What is an Algebraic Expression?

An algebraic expression is an expression which consists of variables, coefficients, constants, and mathematical operators such as addition, subtraction, multiplication and division. Generally, if two things are the same, then it is called equivalent. Similarly, in mathematics, the equivalent expressions are the expressions that are the same, even though the expression looks different. But if the values are plugged in the expression, both the expressions give the same result.

What is the equivalent fraction of 2/3?

For example, if we multiply the numerator and denominator of 2/3 by 4 we get. 2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3.

Is 3y+3 true?

True, because when the numbers are in the parethasis that means you multiply what is outside of the parenthasis like the three by the numbers inside of the parenthasis so 3 x y and 3 x 1, therefore 3y+3 and 3 (y+1) is true.

Is 3y+3 a simplified expression?

The expressions 3y+3 and 3 (y+1) are equivalent expressions. Because 3 (y+1) can be simplified as 3y+3.
