Question

Mutiply the polynomial (x - 6)(x^2 + 2x - 4)

Answer 1

x^3 − 4x^2 − 16x + 24

Explanation:

(x − 6) (x^2 + 2x − 4)

= (x + −6) (x^2 + 2x + −4)

=(x) (x^2) + (x)( 2x) + (x) (−4) + (−6) (x^2) + (−6) (2x) + (−6) (−4)

=x^3 + 2x^2 − 4x − 6x^2 − 12x + 24

=x^3 − 4x^2 − 16x + 24

Answer 2

the answer is x^3+4x^2-16x+24
