OK, once again, USE THE PARANTHESIS!!!

Please!  Every time you make a post like this, people read it and go "Oh
man, the 89 must be screwed up, I better not buy one!"  The actual truth is
"Oh man, that guy isn't using enough parantheses!"

Enter this:

factor((49)-(36)*(x^2))

And it gives you:

-(6x-7)*(6x+7)
