Question

преобразуйте в многочлен
(с-7)(с²+7с+49)-(с-3)3

Answer 1

$<var>(c-7)(c^2+7c+49)-(c-3)^3 =(c^3-343)-(c^3-9c^2+27c-27)</var>$=$<var>c^3-343-c^3+9c^2-27c+27=9c^2-27c+27-343</var>$$<var>=9c^2-27c-316 </var>$

Answer 2

(c-7)*(c^2+7c+49)-(c-3)3=c^3-343-(c-3)*3=c^3-343-(3c-9)=c^3-343-3c+9=c^3-3c-334
