It is a quadratic equation in X, with two real roots.
X=-3
It also equals 13 12.
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.

I'll do ya one better - 12 plus 8 equals what?
If I have this correct you are asking x^2 + 10^2 = 12^2 Then x=6.633249507108
