Polynomials

Sharpen the factoring skills of young algebraists with this skills practice activity. Focusing on the long division of polynomials, these problems challenge students to factor, graph, and describe polynomials of varying degrees.

For this Algebra II/college level worksheet, students use the discriminate to determine if a polynomial has factors with integral coefficients and factor polynomials, including factoring by pulling out the GCF and factoring by grouping....

Though it "sounds like a really fancy word," polynomials prove to be no match for Sal's mathematical skills. After defining the term and providing a few examples, Sal works through a few equations that add or subtract polynomials,...

Adding two polynomials begins with simplifying when possible. Sal demonstrates the process he uses to combine like terms and explains why the process works. This video would be great for those who need a quick refresher.

Sal completes a practice problem to reinforce and apply the concepts learned in previous Khan videos on multiplying polynomials. This would be a great practice problem to do with your students.

While explaining how to add polynomial expressions with multiple variables, Sal uses academic vocabulary and a clear thinking process. This video is relatively short and would be appropriate for students working on homework or prepping...

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...

Some polynomials, when multiplied, result in a special product. Sal uses the distributive property to demonstrate the multiplication process. He then explains why some polynomials cannot be completely simplified.

Investigate polynomial multiplication with the TI-nspire handheld calculator. Using the applications on this calculator, learners explore multiplication of numbers, binomials, a binomial by a polynomial, and polynomials. The dynamic...

Subtract polynomials? Huh? First off find the additive inverse of the number you are subtracting. Next rewrite the polynomials one on top of the other. Make sure to line up the like terms and then write in placeholders. Now add the terms...
