I'm shooting for a BC in computer science, hence I need to take numerous mathmatics courses. Well the sad part is I'm REALLY awful at factoring and I'm all the way into Business Calc at this point. So can someone please factor this one for me?
-x^2 - 36x + 6400 = 0
This is embarrassing.

80 = x + 6x
80 = 7x
x=11.428.....
Probably wrong.
