Question

преобразуйте в многочлен выражение: -(v-5)в кубе-(v+2) (v+3)

Answer 1

$-(v-5)^3-(v+2)(v+3)=\\=-(v^3-15v^2+75v-125)-(v^2+2v+3v+6)=\\=-v^3+15v^2-75v+125-v^2-5v-6=\\=-v^3+14v^2-80v+119$

Answer 2

(v-5)³-(v+2)(v+3)=v³-3*5v²+3*25v-5³-(v²+2v+3v+6)=v³-15v²+75v-125-v²-5v-6=v³-16v²+70v-131

Answer 3

(v-5)³-(v+2)(v+3)=v³-3*5v²+3*25v-5³-(v²+2v+3v+6)=v³-15v²+75v-125-v²-5v-6=v³-16v²+70v-13
