D) $-12 x^{8}+40 x^{4}-16$

Question

Quizplus · Accepted Answer

When multiplying polynomials, distribute the term outside the parenthesis across each term inside the parenthesis and add the exponents for like bases. Thus, $-4x^8(3x^8) = -12x^{16}$, $-4x^8(-10x^4) = 40x^{12}$, and $-4x^8(4) = -16x^8$.

Multiply - −4x8(3x8−10x4+4)-4 x^{8}\left(3 x^{8}-10 x^{4}+4\right)−4x8(3x8−10x4+4) A) −12x16+40x12+4-12 x^{16}+40 x^{12}+4−12x16+40x12+4 B) −12x16−10x4+4-12 x^{16}-10 x^{4}+4−12x16−10x4+4
