Решить1) (y-1) ^2 + 2y-2 y-3 3y = 52) 2x+2 5 x+1 + 10 = x3) 4z^3-z z-2z=0

1) (y - 1) ² + 2y - 2y - 1y = 5.

y² - 3y - 4 = 0,

D = 9 + 4 * 4 = 25,

y₁ = (3 + 5) / 2 = 4,

y₂ = (3 - 5) / 2 = - 1.

2) 2x + 25 х + 1 + 10 = x.

26x = 11,

x = 11/26.

3) 4z³ - z * z - 2z = 0. Поделим уравнение на число z:

4z³ - z ² - 2z = 0.

4z² - z - 2 = 0.

D = 1 + 4 * 4 * 2 = 1 + 32 = 33,

z₁ = (1 + √33) / 8,

z₂ = (1 - √33) / 8.
