8a² - 4b + 7a² and 5(3a² - 2b) + 6

First, simplify the expressions.

1) 8a² - 4b + 7a²

Add like terms.

15a² - 4b

2) 5(3a² - 2b) + 6

Distribute 5 by multiplying the number to each terms inside the parenthesis.

15a² - 10b + 6

15a² - 4b ≠ 15a² - 10b + 6

Solution: The expressions are not equivalent.
