You can put this solution on YOUR website!
Distribute each term in the 1st set of parenthesis into the second set of parenthesis then add your like terms.
You said you only wanted to know if you were right.
I'm sorry, you'll have to try again.
The answer is m%5E4-m%5E3n-19m%5E2n%5E2%2B22mn%5E3-6n%5E4
If you want to see how to get that answer let me know. It helps when doing a long one like this to do it vertically, put your variables in alphabetical order when you multiply(ex. b*a=ab), line up the like terms under the like terms and then add. I can't show you this vertically online, but trust me it helps.
Happy Calculating!!!
