Решите уравнение: 8 корней из x-2 = - x + 4

8 V (X - 2) = - X + 4

64 * (X - 2) = 16 - 8X + X^2

64X - 128 - 16 + 8X - X^2 = 0

-X^2 + 72X - 144 = 0

D = 5184 - 4 * (-1) * (-144) = 5184 - 576 = 4608 = 128 * 36 = 36 * 4 * 32 = 36 * 4 * 4 * 4 * 2

V D = 6 * 2 * 2 * 2 * V 2 = 6 * 8 * V 2 = 48V2

X1 = (- 72 + 48V2) : (-2) = (36 - 24V2)

X2 = (-72 - 48V2) : (-2) = (36 + 24V2)

...

X - 2 > 0

X > 2

...

Ответ: (36 - 24V2) и (36 + 24V2)
