How to simplify a polynomial:
first we do the operations in the brackets using foil so
-A squared times 3A squared=3A fourth
-A squared times (-) A = (-) A cubed
-A squared times (-) 1=(-)A squared
And then you do the same process but instead using +2
Then you bring everything down to the next bracket carrying the (-) 3
Add like terms and then multiply by the outside term.
