Factor 9x^(2n + 3) + 18x^(5n + 1)

I did the following:

9*x^n*x^n*x^3 + 9 * 2 *x^n*x^n*x^n*x^n*x^n + x

Is this correct so far? Thank you!
 
\(\displaystyle \L 9x^{2n + 3} + 18x^{5n + 1} = 9x^{2n + 1} \left( {x^2 + 2x^{3n} } \right)\)

Why in the world would you waste that time?
Moreover, the way you expanded it is completely wrong as far as I can read what you posted.

its not wasting time.... if you can ..can you show me teh steps..because if i have another problem like this i can do it ..with the help of teh steps that you show me.
 
Do you know the difference between "teh" and "the"?
How many of the problems that you have posted have you actually tried to solve?
It appears to me as if you do very little towards your own problems.
The idea is to find the most efficient way to do these problems.
To ‘factor’ means to simplify in the most efficient steps.
So, why do steps that are clearly unnecessary?

By the time you're working on exercises of this level, you shouldn't still be asking the questions you are. To show you "all the steps" would require hours of lessons, covering the various background topics you appear (from what little work you've shown) not yet to have seen.

It might be good to conference with your academic advisor about being placed in a class covering this necessary background material. I'm afraid it simply isn't possible for us to replicate this missing semesters of lessons here. Sorry.

My best wishes to you.
