Khan Academy: Polynomial Basics: Interesting Polynomial Coefficient Problem

Use this video to build mathematical vocabulary through practical application. Sal breaks down the parts of a polynomial expression, identifying the coefficient and exponents while he defines them.

Divide two polynomial expressions by writing the problem as a fraction or as long division. Sal shows how to use long division to divide polynomials. A solid understanding of polynomial operations is necessary to grasp this video.

This video has a basic example of simplifying a polynomial expression with multiple variables.

Explains what like terms are and demonstrates how to simplify a polynomial.

This video shows how to write a polynomial expression for a given situation.

This video demonstrates how to write a polynomial that represents the difference between the area of a rectangle of given length and width and the area of a circle with a given diameter.

A continuation of the video Introduction to Interest also from the Khan Academy. This segment develops formulas for both simple and compound interest using the variables P, r and t. After each of the formulas are derived, they are used...

This video demonstrates how to subtract polynomials when there are multiple variables in each polynomial.

This video demonstrates how to simplify an expression that involves both addition and subtraction of polynomials.

Video reviews the basics of the regression line, then shows how the formula for the coefficient of determination or r squared is derived. Explains how to interpret the coefficient of determination. [12:41]
