http://www.freemathvideos.com In this video tutorial I show you how to factor a trinomial when a is greater than one. We do this by either guess and check or using the diamond to find two values that multiply to give us a
*c and add to give us b. We then use those two values and either finish factoring by using the box method or factoring by grouping. We can then check our answer by multiplying back our two binomials.
4x^2 = -x + 3
