Question 859735: Factorise each of the following as fully as possible.
(a-b*b)- b*b

You can put this solution on YOUR website!
b*b is equal to b^2
(a - b*b) - b*b is equal to a - b^2 - b^2
the parentheses don't do anything to this problem because the order is the same with or without them.
combine like terms to get a - 2b^2
that's as simple as you can get it.
