Topics
We reviewed polynomials and continued with algebraic operations involving polynomials:
We mentioned again how the graph of a quadratic polynomial is a parabola–in particular, we sketched the graph of y = x^2:
We went through a few examples of simplifying polynomial expressions via multiplying (including an example from the PatrickJMT video):
An example from the “Polynomials-Powers of Monomials/Binomials” set:
We closed with some examples of factoring polynomials by finding the GCF (greatest common factor), from the “Polynomials-GCF and Factor by Grouping” sets:
