When asked to factor a quadratic equation such as 2x^2 - 7x -15, many students are uncomfortable with the guess and check method. I created this video to describe a 7 step method that requires NO GUESSING.

^{2}= 2x - 4/5^{2 }- 2x +4/5 =0 but now i'm sure what to do next...do I factor or get rid of the fraction part?^{2}- (5/2)x + 1 = 0^{2}- 2x + (4/5) = 0^{2}- 10x + 4 = 0^{2}- 4(4)(4))---------------------------

2(4)

-------------------

^{2}- 5x + 2 = 0^{2}- 4(2)(2))-----------------

^{2}- 5x + 2 = 0
