Question

Factor please:
8x^2-6x-9=0

Answer 1

need to know how to do it and why please

Answer 2

8x^2 - 6x - 9 = 0

ac = 8(-9) = - 72

Factors of - 72 that add to - 6 are +6 & - 12

8x^2 + 6x - 12x - 9 = 0

2x(4x + 3) - 3(4x + 3) = 0

(2x - 3)(4x + 3) = 0

x = 3/2, - 3/4

Answer 3

hang on lemme process this

Answer 4

Why is it (2x-3) (4x+3)=0 did u skip a step?

Answer 5

No that is the process after factoring

Answer 6

Plug in the numbers, factor, and you receive the solution
