Step-by-step explanation:

factories by factors method:--

2x^3+9x^2+ 7x-6

= 2x^3 - x^2 + 10x^2 - 5x +12x -6

= x^2(2x-1)+5x(2x-1)+6(2x-1)

=(2x-1)(x^2+5X+6)

=(2x-1)(x^2+3x+2x+6)

=(2x-1)(x+3)(x+2)

I hopes its helps u.

Answer 2

Answer:

value of x will be -2

Step-by-step explanation:

$f(x) =2x^{3} + 9x^{2} + 7x - 6\\f(x) =2(-2)^{3} + 9(-2)^{2} + 7(-2) - 6\\f(x) = -16 + 36 -14 - 6\\f(x) = 36 - 36\\ f(x) = 0$
