Question

Solve by factoring: show all work
4x^2 + 8x − 5 = 0

Answer 1

4x^2 +10x -2x -5 =0
2x (2x +5) -1(2x +5) =0
(2x +5) (2x -1) =0
Solve
2x +5 = 0 or 2x -1 =0
x = -5/2 or x = 1/2

Answer 2

4x^2 + 8x − 5 = 0
4x^2 +10x-2x − 5 = 0
2x (2x +5) -1(2x +5) =0
(2x +5) (2x -1) =0

2x +5 = 0 or 2x -1 =0 x = -5/2 or x = 1/2
