This is an interesting problem that approaches higher degree polynomials from a different perspective. Given a third degree polynomial, two known zeros, and a y-intercept, find the value of the polynomialÕs coefficients. This problem...

Sal takes polynomial equations in the other direction with this video where he shows how to factor them instead of adding or multiplying them. He has two goals in this activity: first, to show how to factor polynomial equations, and then...

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,...

First clarifying that people need to "resist every temptation on earth" when squaring a binomial, Sal walks viewers through a few equations using binomials and applies the skills from the previous videos about working with polynomials....

Everyone can be shortcut-savvy with this video, which features Sal multiplying "a ton of polynomials" in clear, easily understandable terms. Those who have a hard time applying old concepts to new equations will rest assured with the...

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...

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...

Explore the concept of polynomials and determine the value and number of zeros for a given polynomial using the Rational Root Theorem. Then graph the polynomials and relate the number of zeroes to the degree of the polynomial.

At times, polynomial expressions can be very long. Watch this video to see how Sal simplifies them by combining like terms. He explains his process and uses various colors to demonstrate why like terms are alike and why they can be...

Can you multiply a monomial by a polynomial? Yes you can, if you use the distributive property. Sal describes how to distribute the monomial term over the entire polynomial expression. He does a wonderful job explaining this concept.

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.

Sometimes you'll need to solve an equation with multiple variables on each side. This step-by-step tutorial will show you how to set your equation to 0, factor out the GCF, simplify, write your answers as a set, then plug and chug to...

It's not a complicated word problem, but the picture frame just gives the problem a little context. So you are trying to find the difference, which means subtraction. The instructor reviews how to distribute the negative sign to the...

Use prime factorization to find the greatest common factor of four given values. What are the factors that all four given values have in common? Identify them, and then multiply together to get the greatest common factor. Just like that....

Have you ever heard of the FOIL method? Watch and learn how the FOIL method can be used to help you multiply binomials. It all starts with a tic-tac-toe box and two polynomials then ends with a correct answer.

This clip is great! Your budding algebra experts will have no trouble understanding what the degree in a polynomial means. The degree is compared to a mountain range, the highest peak in the range usually names the entire set of...

Practice FOILing binomials and then practice factoring. Many of the problems are binomials set up to be relatively easy to factor. Once factored, they need to then be checked by FOILing. Most of the problems are polynomials in the 2nd...

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...

The instructor demonstrates how to line up two polynomials vertically to add them together. She emphasizes lining up the terms with the same powers. She also identifies some places where there is no term and shows how to write a...

It's not a complicated word problem, but the picture frame just gives the problem a little context. So you are trying to find the difference, which means subtraction. The instructor reviews how to distribute the negative sign to the...

Apply the distributive property to multiply a monomial times a polynomial to get the area of a rectangle. Then use this information to solve a word problem.

FOIL it! What? You want to multiply two binomials then use the FOIL method: First, Outside, Inside, Last. When you have done that, your final steps is to combine the like terms.

A rational function can be written as a ratio of two polynomials. There are a couple of rules concerning the denominator so watch this video and find out what they are.

The teacher explains the many steps in simplifying a rational expression using opposite binomial factors. At first it seems complicated but if you follow along and watch out for your negative numbers you can learn how to simplify this...
