Hello @patientwithme :)

would you just like to simplify this?
first let's distribute the  minus into the parenthesis
for example
- (a + b - c) = -a - b + c

no prob :P

@patientwithme don't forget you can only combine (add or subtract) like terms-meaning they are the same letter (x, y, z, whatever it may be) and they have to be raised to the same powers. So you can't add a x^2 with a plain x.
