This course contains 9 segments:
Intro to polynomials
Learn about polynomial expressions: What are they? How are they constructed? What can we do with them?
Adding & subtracting polynomials
Learn how to add and subtract polynomial expressions with one variable.
Adding and subtracting polynomials: two variables
Learn how to add and subtract polynomial that involve two variables. For example, x^3 + xy + 3y - (x^3 + 6xy + 2y^2).
Multiplying monomials
As an intro to more elaborate polynomial multiplication, learn how to multiply monomials (which are polynomials with a single term). For example, multiply 2x³ and 5x⁷.
Multiplying monomials by polynomials
Learn how to multiply a polynomial expression by a monomial expression. Monomials are just polynomials with a single term!
Multiplying binomials
Learn how to multiply two binomials together. For example, (3x - 7) * (10x + 2).
Multiplying binomials by polynomials
Learn how to multiply a polynomial expression by a binomial expression.
Special products of binomials
Learn about the special types of products of binomials: perfect squares and the difference of two squares. These will be very helpful once you tackle more advanced expressions in Algebra.
