(х² - 1)² + (х - 1) = 0
((x - 1)(x + 1))² + (x - 1) = 0
(x - 1)*((x - 1) * (x + 1)² + 1) = 0
x - 1 = 0 (x - 1) * (x + 1)² + 1 = 0
x = 1 (x - 1) * (x² + 2x + 1) + 1 = 0
x³ + 2x² + x - x² - 2x - 1 + 1 = 0
x³ + x² - x = 0
x(x² + x - 1) = 0
x = 0 x² + x - 1 = 0
D = 1² + 4 * 1 * 1 = 5
x = (-1 - √5)/2
x = (-1 + √5)/2

Объяснение:
5x2 = 12-3
5x2 =9
5x2= 12-10
m=10
5x2 + 103-12 = 0
0=0
