Question 159645: Please explain to me how to factor polynomials. I need it broken down step by step. When to use formulas (a+b)^2= (a+b)(a+b)=a^2+2ab=b^2 or (a+b)(a-b)=a^2-b^2 or a^3 +b^3= (a+b)(a^2-ab=b^2) etc.
Here's a problem, for example:
Factor: 28y^2-13y-6
Thank you!

28y^2-13y-6
(7Y+2)(4Y-3)
------------------
7Y+2
4Y-3 MULTIPLY
---------------------
28Y^2+8Y-21Y-6
28Y^2-13Y-6
