<h2>Answer:</h2>
-18x^5-204x^4-722x^3-600x^2+672x-128
<h2>Explanation:</h2>There are multiple ways to solve this for example the foil method or the box method. I prefer to do the box method.
First we are going to set it up
After we set it up we have to solve it so first we are going to multiply
We have to add the exponent
Now we have to add them
-18x^5 stays because there is nothing to add to
Now we add the rest
And -128 stays the same
The answer is
-18x^5-204x^4-722x^3-600x^2+672x-128
The only thing you can do here is to try to simplify, so I'll assume that's what you want to do.
The numerator is a difference of squares, so it's easy to factorize:
In the denominator, we factorize by grouping:
So we have
