Question

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

Answer 1

Пошаговое объяснение:

Answer 2

$- 2x {}^{2} - 2x + 5 = - x {}^{2} - x - (1 + 2x + x {2)}^{}$

$- 2x {}^{2} - 2x + 5 = - x {}^{2} - x - 1 - 2x - x {}^{2}$

$- 2x {}^{2} + 5 = - x {}^{2} - x - 1 - x {}^{2}$

$- 2x {}^{2} + 5 = - 2x {}^{2} - x - 1$

$5 = - x - 1$

$x = - 1 - 5$

$x = - 6$
