You can write equivalent expressions by combining like terms . Like terms are terms that have the same variables raised to the same powers. For example, the list shows some pairs of like terms. the new coefficient is 9.
What is an example of an equivalent expression?
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(x 2 + 2y + 1) = 6x 2 + 12y + 6.
How do you do equivalent expressions?
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical , then the two expressions are equivalent.
