You can put this solution on YOUR website! Like terms are those that have exactly the same letters and raised to exactly the same powers. This is like the story of creation from the book of Genesis in the Bible. If they are LIKE TERMS, you ADAM together! If they are NOT LIKE TERMS, then you must EVE it alone!!
Now, since you did NOT intend for there to be a double negative sign before the 3ab, I have corrected it as follows. This should be what you were expecting:
5ab-7ab^2-3ab-12ab^2+10ab-9ab^2
5ab-7ab^2-3ab-12ab^2+10ab-9ab^2
5ab-3ab+10ab-7ab^2-12ab^2-9ab^2
Now, combine the ab terms: 12ab
Combine the ab^2: -28ab^2
Final answer: 12ab-28ab^2
R^2
