Question

solve x^2 +4x +4 =0

please help me

Answer 1

x^2 + 2x + 2x + 4 = 0

x(x + 2) + 2(x + 2) =0

(x + 2) (x + 2) = 0

x = -2, / x = -2......

hope it's help you....

Answer 2

${x}^{2} + 4x + 4 = 0 \\ {x}^{2} + (2 + 2)x + 4 = 0 \\ {x}^{2} + 2x + 2x + 4 = 0 \\ x(x + 2) + 2(x + 2) = 0 \\ (x + 2)(x + 2) = 0 \\ \\ x + 2 = 0 \\ x = - 2$
