Решите уравнение 7x-4x (x-5) = (8-2x) (8+2x) + 27x

7x-4x (x-5) = (8-2x) (8+2x) + 27x

7x-4x²+20x=64+16x-16x-4x²+27x

7x-4x²+20x-64-16x+16x+4x²-27x=0

0x=0

x=0

ответ: 0

(x-2) (x+2) (x²+4) (x^4+16) = x^8+10x

(x²-4) (x²+4) (x^4+16) = x^8+10x

(x^4-16) (x^4+16) = x^8+10x

(x^8-256) = x^8+10x

x^8-256-x^8-10x=0

-10x=256 |: (-10)

x=-25.6

ответ:-25,6
