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

    (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

  • Algebra III - ,

    Glad you got it!
