Question

Quizplus · Accepted Answer

To multiply $(x+10)(-5x+5)$, distribute each term in the first polynomial across the terms in the second polynomial: $(-5x)(x) + (-5x)(10) + 5(x) + 5(10)$, which simplifies to $-5x^2 - 50x + 5x + 50$, or $-5x^2 - 45x + 50$.

Multiply - (x+10)(−5x+5)(x+10)(-5 x+5)(x+10)(−5x+5) A) −5x2−45x−45-5 x^{2}-45 x-45−5x2−45x−45 B) −5x2−47x+50-5 x^{2}-47 x+50−5x2−47x+50 C) −5x2+50x−45-5 x^{2}+50 x-45−5x2+50x−45
