3^2x - 6 x 3^x + 9 = 0

Solve for x

I have no Idea what to do

• Algebra III -

sorry, the x in between 6 and three is multiplication... so it should be

3^2x - 6(3^x) + 9 = 0

• Algebra III -

I am going to rewrite the equation for you

(3x)2 - 6(3x) + 9 = 0

there is a strong hint there.

• Algebra III -

ahhh its a perfect square trinomial

(3^x - 3)^2 = 0

so x = 1
