Question

Quizplus · Accepted Answer

When multiplying polynomials, you distribute the term outside the parenthesis across each term inside the parenthesis. Here, $-10x^4$ is multiplied by each term inside the parenthesis, resulting in $-50x^{11} + 30x^4$, because you add the exponents when multiplying terms with the same base.

Multiply - −10x4(5x7−3)-10 x^{4}\left(5 x^{7}-3\right)−10x4(5x7−3) A) −20x4-20 x^{4}−20x4 B) −50x7+30-50 x^{7}+30−50x7+30 C) −50x11−3-50 x^{11}-3−50x11−3
