Question

(x²-x-12) ( x-4) what's the answer plsss​

Answer 1

Answer:

X^2-X-12=0

X^2–4X+3X-12+0

X(X- 4) +3 (X- 4) =0

(X+3) (X-4) =0

Hence X+3=0 ; X= -3

X-4 = 0 ; X=4

Value of X = -3 & 4

Answer 2

Answer:

x^3-5x^2-8x+48

explanation:

multiplying (x²-x-12) ( x-4)

so that we get x^3-x^2-12x-4x^2+4x+48

adding and subtracting we get

x^3-5x^2-8x+48
