Now with CLEARER PRINT. The "Box Method" is great for factoring polynomials, from the most basic to even the though ones! It's quick and easy. It can be learned in about 10 minutes and mastered in another 5 minutes. Then you'll be able to zip through factoring. It is especially useful for more complex cases, such as when you have a coefficient in front of the x-squared, such as 2(x-squared), 5(x-squared), and when you have a second variable involved, such as 4(x-squared) – 4xy – 15x(y-squared). Suitable for grades 9, 10, 11 and 12.
