Multiplying polynomials in Algebra

In 8th grade algebra we are learning how to multiply polynomials and trinomials. The process is broken up into three different processes: Disributive property, the Matrix method, and the F.O.I.L. method. Distributive property is when you distribute two values and multiply them by the second polynomial((4x+3)(2x-3)= 4x(2x-3)+3(2x-3)). The Matrix method is when you put each polynomial on the outside of a 2 by 2 square and multiply them together. Finally the F.O.I.L. method is when you multiply the first numbers, the outer numbers, the inner numbers and the last numbers. That is what we are lerning in 8th grade Algebra.
