I am not exactly sure if this answer is correct. I ran it through my Calculator and here is what I get..
X2+4x+4=36
= x2+4x-32=0
=x2-4x+8x-32=0
=x(x2/x – 22*x/x) + 23 (23*x/23- 25/23) = 0
= x(x-4) +23 (x-4) = 0
= (x-4) (x+8) = 0
= x - 4 = 0
= x +4 = 0
X = 4
X = -8
X = 4, -8
What are the exact solutions?
x^2+4x+4=36
I have -34,-38
Is this right?

Becky, why did you not substitute your answers back in the equation.
It would have shown you that you are way off,
but Mike's answers work and his solution is correct.
