Question

Quizplus · Accepted Answer

To multiply $(\mathrm{x}-4)\left(9 \mathrm{x}^{2}+\mathrm{x}+7\right)$, distribute each term in the first polynomial across the second polynomial: $9x^3 + x^2 + 7x - 36x^2 - 4x - 28$, which simplifies to $9x^3 - 35x^2 + 3x - 28$.

Multiply - (x−4)(9x2+x+7)(\mathrm{x}-4)\left(9 \mathrm{x}^{2}+\mathrm{x}+7\right)(x−4)(9x2+x+7) A) 9x3−35x2+3x−289 x^{3}-35 x^{2}+3 x-289x3−35x2+3x−28 B) 9x3−37x2+3x−289 x^{3}-37 x^{2}+3 x-289x3−37x2+3x−28
