Find the values for "a" and "b" that would make the equality true. 7 (ay^2+by-3) = 14y^2-7y-21

a = 2 and b = - 1

Step-by-step explanation:

distribute the left side of the equation and compare the like terms with terms on the right side

7ay² + 7by - 21

compare the coefficients of like terms with 14y² - 7y - 21

7a = 14 ⇒ a = 2

7b = - 7 ⇒ b = - 1
