## anonymous 5 years ago how do I solve the quadratic equation x squared plus 4 x plus 4 equals 9

1. anonymous

you substract over the 4 then take the 4th root of that to get your x.

2. anonymous

oh wait.

$x^2 +4x + 4 = 5$ First way:$(x+2)^2 = 9$$x + 2 = \pm 3$ x = 1 or x = -5 Second way:$x^2 + 4x - 5 =0$$(x+5)(x-1) = 0$ x = 1 or x= -5
