Khan Academy: Manipulating Expressions Using Structure

Several examples of different types of algebraic expressions are multiplied. The distributive property demonstrates the steps needed to multiply the terms in the expressions. Sal combines the like-terms at the end of the presentation....

Rewrite an expression containing two unknown variables by choosing a given equation that is equivalent. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Rewrite an expression containing two unknown variables by using a given equation that contains those variables.

Given some information about several unknown variables, rewrite and simplify the structure of an expression containing those variables. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a...

Given some information about several unknown variables, evaluate an expression containing those variables.

Solve advanced equations by strategically using quadratic factorization methods.

Factor complex polynomials (i.e. polynomials of various degrees and or with two variables) using special product factorization methods. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a...

Factor 'advanced' polynomials (i.e. polynomials of various degrees and or with two variables) using special product factorization methods.

Solve advanced equations by strategically using quadratic factorization methods. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice determining whether or not two algebraic expressions are equivalent by manipulating the expressions. These problems require you to combine like terms and apply the distributive property.
