Well, it's not factorable into integer numbers, but any quadratic equation can be factored. Sometime the roots are real numbers, sometime they're irrational number and sometime they're imaginary numbers.
So while this equation can't be factored by inspection, it can be factored using the quadratic formula, giving you two irrational roots -- about 3.92 and 0.31.

It won't factor. You'd need factors of 20 (from 4•5) that add up to 17.

It is not factorable.
Here is a good site explaining how to factor trinomials
http://www.factoring-polynomials.com/factoring-trinomials-5.htm
Actually that website is good for all your algebra homework.
Please make sure you understand why it is not factorable and actually try to work it out, that way you can show your work. Also, keep in mind that you will not have yahoo answers on your test! It is extremely important to be able to understand how to do this on your own.
Good luck and study hard!
