x = -1, -5

Step-by-step explanation:

${(x + 3)}^{2} = 4 \\ = {x}^{2} + 2 \times x \times 3 + {3}^{2} = 4 \\ = {x}^{2} + 6x + 9 = 4 \\ = {x}^{2} + 6x = 4 - 9 \\ = {x}^{2} + 6x = - 5 \\ = {x}^{2} + 6x + 5 = 0 \\ = {x}^{2} + 5x + x + 5 = 0 \\ = x(x + 5) + 1(x + 5) = 0 \\ = (x + 1)(x + 5) \\ = x = - 1 \: \: or \: \: - 5$
