Question

Identify the factors of x^2 -4x-12 A.(x+4)(x-3) B.(x-4)(x+3) C.(x-2)(x+6) D.(x+2)(x-6)

Answer 1

`x^(2)-4x-12=x^(2)-6x+2x-12=x(x-6)+2(x-6)= \\ \\ =\boxed{\boxed{(x+2)(x-6)}}`

Answer 2

Since there isn't any like terms....then we have to factorize it.


Factor x^2−4x−12

x^2−4x−12

=(x+2)(x−6)

Answer is D.
