3^2x  6 x 3^x + 9 = 0
Solve for x
I have no Idea what to do

sorry, the x in between 6 and three is multiplication... so it should be
3^2x  6(3^x) + 9 = 0 
I am going to rewrite the equation for you
(3^{x})^{2}  6(3^{x}) + 9 = 0
there is a strong hint there. 
ahhh its a perfect square trinomial
(3^x  3)^2 = 0
so x = 1 
Glad you got it!
