Help I have a C in math. I don't understand this Alegbra. If you get it right then I will give you Brainlist!

This is the same as writing [tex]-18w^7[/tex]
=====================================================
Explanation:
The three terms we are multiplying are:
The coefficients of those terms are: 3, 2, -3
Multiplying the coefficients gets us 3*2*(-3) = -18 which is the coefficient of the final answer.
As for multiplying the w terms, we add the exponents: -2+6+3 = 7, and this is the exponent of the final answer.
Wrapping everything up, that's how we end up with -18w^7
