Using a basic polynomial equation of the form ax^2 + bx + c

If a = 1, then the factoring is done this way:

(x+h)(x+k) where h+k=b and h*k=c

If a `!=` 1, then the factoring is done this way:

(mx+h)(nx+k), where m*k+n*h = b and h*k=c

 

Another simplier way to factor a polynomial is to graph the equation and find the x-intercepts.  The opposites of the x-intercepts equal h and k.
