(x +5)(x²-5x+25)=x³+25-10x

Question

(x +5)(x²-5x+25)=x³+25-10x

Answer 1

(x +5)(x²-5x+25)=x³+25-10x
x³+125=x³+25-10x
125=25-10x
10x=25-125
10x=-100
x=-100:10
x=-10
ОТВЕТ: -10

Спасибо большое

Answer 2

(x + 5)(x² - 5x + 25) = x³ + 25 - 10x
x³ - 5x² + 25x + 5x² - 25x + 125 - x³ - 25 + 10x = 0
10x = - 100
x = - 10
