Chapter 5 - Section 5.8 - Solving Equations by Factoring and Problem Solving - Exercise Set: 8

Answer

{-2, 7/3}

Work Step by Step

1. Factor: 3$y^{2}$ - y - 14 = (3y - 7)(y + 2) 2. Apply the zero factor property to the factored expression: a) 3y - 7 = 0 b) y + 2= 0 3. Solve each linear equation: a) y = 7/3 b) y = -2 The solutions are {-2, 7/3}.
