First, we break up the numerator into its individual terms and write each term over the denominator. We need to deal with the numerator on its own terms. It doesn't like being trifled with.
Then we simplify each new term to find
2x3 + 4x2 + 3x.
Write as a sum of integers.
Pull out a common factor of 2 from the numerator and the denominator, giving us
We cancel the 2s to find
1 + 2 + 3 + 4.
Pull out the common factor of 10x2 to find
and cancel to find
Make it rain.
