Step 2.1
Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of .
++++
Step 2.2
Divide the highest order term in the dividend by the highest order term in divisor .
++++
Step 2.3
Multiply the new quotient term by the divisor.
++++
+++
Step 2.4
The expression needs to be subtracted from the dividend, so change all the signs in
++++
---
Step 2.5
After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.
++++

-
Step 2.6
The final answer is the quotient plus the remainder over the divisor.
Step 3
Split the single integral into multiple integrals.
Step 4
Apply the constant rule.
