Question

2x^2 + 5x - 12 = 0 solve by factoring. Show your work.

Answer 1

Answer:

x = (-3/4), 4

Step-by-step explanation:

2x² + 5x - 12 = 0

2x² + 3x − 8x − 12 = 0

2x • (x - 4)   3 • (x - 4)

(2x + 3)  •  (x - 4)

(2x + 3)(x − 4) = 0

2x + 3 = 0

      -3   -3

2x = -3

x = (−3/2)

x − 4 = 0

  + 4  + 4

x = 4
