(9x^3+3x^215x)?(3x)

Is the ? divided by??
If so you are dividing a trinomial by a monomial
you just divide each term of the trinomial by the monomial
9x^3 divided by 3x
3x^2 divided by 3x
15x divided by 3x
Remember to divide the coefficients (numbers out in front)
Then for the x's with the exponents. Keep the x and subtract the exponents.
The first one will have x^2 in the answer.
Do you need more help or are you okay now?
