ПОМОГИТЕ ПЖ!!!!!!!!!!!!!!!!!!!!!!!!
(x^2 - 2x)^2 - 11(x + 1)^2= -35

Answer 1

Объяснение:

${(x + 1)}^{2} = {x}^{2} + 2x + 1 \\ {x}^{2} +2x = y \\ \\ {y}^{2} - 11y - 11 + 35 = 0 \\ {y}^{2} - 11y + 24 = 0 \\ y = 3 \\ y = 8$

${x}^{2} + 2x - 3 = 0 \\ x = - 3 \\ x = 1 \\ \\ \\ {x}^{2} + 2x - 8 = 0 \\ x = - 4 \\ x = 2$
