A) $- 4 x ^ { 2 } - 41 x + 108$
B) $- 4 x ^ { 2 } + 108 x - 39$
C) $- 4 x ^ { 2 } - 39 x + 108$

Question

Quizplus · Accepted Answer

To multiply the given expressions, distribute each term in the first polynomial across each term in the second polynomial: $(-4x \cdot x) + (-4x \cdot 12) + (9 \cdot x) + (9 \cdot 12)$. This simplifies to $-4x^2 - 48x + 9x + 108$, which further simplifies to $-4x^2 - 39x + 108$.

Multiply - (−4x+9)(x+12)( - 4 x + 9 ) ( x + 12 )(−4x+9)(x+12)

Multiply
- $( - 4 x + 9 ) ( x + 12 )$
