POLYNOMIALS

To start with this lesson, we are going to review the vocabulary regarding "POLYNOMIALS" that we studied last year. Click on the image to watch a presentation.



Here you are something very IMPORTANT that we didn´t study last year: Special products of binomials:
    1. The square of a SUM
    2. The square of a DIFFERENCE
    3. The product of a SUM and a DIFFERENCE

This year, we are going to divide polynimials using long division (the usual way) and a new way of dividing, called Synthetic Division (Ruffini´s rule), that can be used to divide polynomial by a binomial of the form (x+k) or (x-k). Here you are some exercises to do regarding synthetic division and its applications.
