Question

Преобразовать в многочлен:
1) -2(V+1)(V+4)-(V-5)(V+5)
2) (v-1)(v+2)-(v+7)^3
3) -2(y-5)(y+1)-(y-7)(y+7)
4)-(v-5)v-(v-6)(v+6)
5) (c-1)(c+1)-(c+1)(c+2)

Answer 1

-2(v²+4v+v+4)-(v²-25)=-2v²-10v-8-v²+25=-3v²-10v+17
2) v²+2v-v-2-(v³+21v²+147v+343)=v²+v-2-v³-21v²-147v-343=-v³-20v²-146v-345
3)-2(y²+y-5y-5)-(y²-49)=-2y²+8y+10-y²+49=-3y²+8y+59
4)-v²+5v-v²+36=-2v²+5v+36
5)c²-1-(c²+2c+c+2)=c²-1-c²-3c-2=-3c-3
