(x-6)(x+2)
Change it into this equation (5^2)^(2x)=5^(x^2-12)
therefore x=6 or x=-2
25 = 5^2 left side (5^2)^(2x) then multiply exponents and get 5^4x
if 5^4x = 5^(x^2-12) since the bases are the same you just have 4x = x^2 - 12, now factor or use the quadratic formula

25^(2x)=5^(x^2-12) 5^4x = 5^(x^2-12) we have the same base 5 therefore \[4x=x^2-12\] \[0=x^2-4x-12\] \[0=(x-6)(x+2)\] x-6=0 x=6 x+2=0 x=-2
