Помогите решить еще уравнения: - 2x^2-2x+5 = - x^2-x - (1+x^2)

и - 2x^2+3x-4 = - x^2-x + (2-x^2)

1) - 2x^2 - 2x + 5 = - x^2 - x - (1+x^2)

-2x^2 - 2x + 5 = - x^2 - x - 1 - x^2

-2x^2 - 2x + 5 = - 2x^2 - x - 1

- 2x^2 + 2x^2 - 2x + x + 5 + 1 = 0

-x + 6 = 0

- x = - 6

x = 6

2) - 2x^2 + 3x - 4 = - x^2 - x + (2 - x^2)

- 2x^2 + 3x - 4 = - x^2 - x + 2 - x^2

-2x^2 + 3x - 4 + x^2 + x - 2 + x^2 = 0

4x - 6 = 0

4x = 6

x = 6/4

x = 1,5
