(-6x² + 9x - (-9))   -   (-7x² +3x - (-8))

I have to simplify this and I got x^2+6x+1  all of my other answers look more like this (x+_)(x+_)   I can't figure out how to simplify this down anymore. Help? Please?

Can you take a pic of the problem? Seeing it from a textbook will help me understand.

This...if you can show a picture of the actual problem I will likely be able to help you a lot more :)

Some of the symbols you used in your equation are unreadible on my computer.

I don't have anything to take a picture with but I did look up the alt code but I spaced it out so maybe it's easier to read..

(-6x² + 9x - (-9))   -   (-7x² +3x - (-8))

(-6x2+9x+9)-(-7x2+3x+8)

-6x2+9x+9+7x2-3x-8

-x2+6x+1

You are right. It should be a positive x squared. That was my bad.
