1. ## ***Need Help with online Math quiz*** Final in 2 weeks

If someone can help me with Factoring polynomials, it would be greatly appreciated . College level*

I have 8 questions on the quiz, I know some of them though some are hard.

Thanks!

8x2(squared) + x - 7 = (8x-_)(x+_)

I forgot how to solve for the other numbers. Is it GFC. Can some one help me?

Consider $\displaystyle (8x - a) (x + b)$ ..... You need to find values of $\displaystyle a$ and $\displaystyle b$ so that when you expand $\displaystyle (8x - a) (x + b)$ you get $\displaystyle 8x^2 + x - 7$. Try a little bit of trial and error .....

Since this is part of an on-line test it's not appropriate to ask for help so I'm closing the thread.
