A quadratic equation have a 4 methods, this is the factoring, extracting, completing and quadratic formula.
Solve this quadratic equation by COMPLETING THE SQUARE
So, the first step is do it's standard form, this is the ax²+ bx = c.
x² + 4x + 4 = 6 + 4
(b/2)² = (2)² = 4
(x + 4)² = 10
√(x + 4) | √10
x + 4 | 10
x + 4 ± 10
