Khan Academy: Algebra: Adding and Subtracting Polynomials 2

For use with a TI-nspire calculator, this lesson focuses on adding and subtracting polynomials. Learners use calculator to add and subtract polynomials using both the vertical method horizontal methods. A class discussion follows the...

Need a unique approach to adding and subtracting polynomials? A helpful math lesson approaches the concept by relating polynomials to base 10. It encourages pupils to see each term as having a specific value, and therefore,...

Define, simplify, add, and subtract polynomials. Identify the degrees of a polynomial. Determine if a polynomial is a monomial, a binomial, or a trinomial. Then look at simplifying a polynomial by combining the coefficient values of like...

Algebra tiles help pupils understand many different algebra topics. The video explains the process of adding and subtracting polynomials using the tool. Seeing the terms as individual tiles helps learners understand the idea of a...

To subtract two polynomials Sal demonstrates that you add the opposite of the second term, and then combine like terms to solve. How do you find an opposite term? Simply multiply the polynomial by -1. This video is very clearly explained...
