Question

Помогите пожалуйста решить уравнение (х+2)^2 – 1 = х + 3

Answer 1

${(x + 2)}^{2} - 1 = x + 3 \ (x + 2 - 1) times (x + 2 + 1) = x + 3 \ (x + 1) times (x + 3) = x + 3 \ (x + 1) times (x + 3) = 0 \ ((x + 1) - 1) times (x + 3) = 0 \ x times (x + 3) = 0 \ x = 0 \ x + 3 = 0 \ x = 0 \ x = - 3 \ x1 = - 3.x2 = 0$
