Question

X^3+3x^2-4x-12=? Hint p(2)=0

Answer 1

Step-by-step explanation:

since p(2)=0

this implies that x-2 is the factor of above polynomial

Dividing the polynomial by x-2

x^2+5x+6

x^2+2x+3x+6

X(x+2)+3(x+2)

(x+2)(x+3)

therefore the factors.of the polynomial is

(x-2)(x+3)(x+2)

(x^2-4)(x+3)[using (a-b)(a+b)= a^2-b^2]
