Question

Simplify: (2x - 3)(x^2 - 4x - 6)
A. 2x^3 - 11x^2 - 18
B. 2x^3 - 11x^2 - 24x + 18
C. 2x^3 - 11x^2 + 18
D. 2x^3 - 11x^2 - 24x - 18

Answer 1

it multiplies out to \[2x^3-3x^2-8x^2+12x-12x+18\]
\[-3x^2-8x^2=-11x^2\]
\[+12x-12x=0\]

so the whole thing can be simplified to\[2x^3-11x^2+18\]
this is answer C
