how do I solve log base 2 of 20?
Solve it for what? There's no variable, and it's not an equation.
You can evalute it, or calculate it.

-------------------
If it's actually x^2:
(x+4)*(x-2) = 0
x = -4, 2
-4 won't work, it gives the log of a negative number
x = 2

x sq + 2x - 3 = 0
(x - 2)(x + 1)= 0
x - 2 = 0 x + 1 =0
x=2 x= -1
