Khan Academy: Algebra Ii: Zeros of Polynomials (With Factoring)

Put your math pupils’ division and algebra skills to the test with this video, which introduces the concept of polynomial division. Sal's examples increase in complexity as the video progresses, allowing viewers to see how basic skills...

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...

The zeros of a polynomial p(x) are all the x-values that make the polynomial equal to zero. They are interesting to us for many reasons, one of which is that they tell us about the x-intercepts of the polynomial's graph. We will also see...

When we are given the graph of a polynomial, we can deduce what its zeros are, which helps us determine a few factors the polynomial's equation must include. [3:00]

Select the graph that best suits a polynomial equation by considering the zeros of the polynomial. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Demonstrates how to solve a quadratic equation by factoring where the first step is to set the equation equal to zero. The quadratic polynomial in the example is a perfect square trinomial. [3:19]

Use various methods in order to find all the zeros of polynomial expressions or functions using this five-question quiz.

A video lesson that goes through four example problems dealing with conic sections. Topics covered include: finding the vertex of a parabola from its equation; finding the asymptotes of a hyperbola and then sketching its graph;...

A step-by-step instructional video on how to solve a ratio problem using algebra. [9:58]

Video demonstrates solutions to four problems from the California Algebra II released state test questions including factoring polynomial expressions, adding and dividing rational expressions, and applying exponent rules. [10:19]
