factor trinomial 9x(2) + 9x + 2

i do not know how to type the 9x and the little x over the 2 ( to the x power ) thank you for your help.

  • algebra -

    so you mean
    9^(2x) + 9x + 2 ?

    if so, ....
    let 9^x = y
    then your expression becomes
    y^2 + y + 2

    which does not factor, so the original does not factor.
