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 
Reiny,
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.
