Question

A equação (x + 2)(x + 2) = 2x +7

Answer 1

$(x + 2)(x + 2) = 2x + 7 \\ (x + 2 {)}^{2} = 2x + 7 \\ {x}^{2} + 4x + 4 = 2x + 7 \\ {x}^{2} + 4x + 4 - 2x - 7 = 0 \\ {x}^{2} + 2x - 3 = 0 \\ x \times (x + 3) - (x + 3) = 0 \\ (x + 3) \times (x - 1) = 0 \\ x + 3 = 0 \\ x - 1 = 0 \\ x = - 3 \\ x = 1$
