Factoring is a process of turning a sum or difference into a product. Many times students think of this in terms of how length times width of a rectangle is equal to the area. The trinomial we're given represents the area, and draw a 2 x 2 box to show the pieces of the area. The upper left box must be x-squared, and the bottom right must be the "c" value. We guess and check the remaining two diagonal boxes to get a sum of "b". The length and width labels represent the binomial factors of the original trinomial "area."
