Question

Упростите выражения: (x-10)(x²+10x+100)-x³ y³+(7-y)(49-7y+y²) 216-(a+6)(a²-6a+36) 600-(8-z)(z²+8z+64)

Answer 1

(x-10)(x²+10x+100)-x³= -1000   
y³+(7-y)(49-7y+y²)(7-y)= 343-98у плюс 14у в квадрате

Answer 2

1 (x-10)^3-x^3= (x-10-x)(x^2+10x+100)=-10(x^2+10x+100)
2.y^3+(7-y)^3=(y+7-y)(y^2-y(7-y)+(7-y)^2)=7(y^2-7y+y^2+49-7y-y^2)=7(-14y+y^2+49)
