2x

^{2}+4x + 4 = 0We can factor a 2 out of each coefficient and the constant

2(x

^{2}+ 2x + 2) = 0Dividing both sides by 2 reduces your equation to

x

^{2}+ 2x + 2 = 0a = 1, b= 2, c = 2

x = [-b ±√(b

^{2}-4ac)]/2a from quadratic equationx = [-2 ±√[2

^{2}-4(1)(2)]]/(2)(1) = [-2 ±√(4-8)]/2

= [-2 ±√(-4)]/2

= (-2 ± 2i)/2

= -1 ± i
