[Free Registration/Login may be required to access all resource tools.] This lesson covers solving equations where the variable has a rational exponent.

Construct an equation or an inequality that model a given context. Modeling expressions can be quadratic, rational, or exponential.

Solve linear equations that contain expressions with parentheses and the coefficients are rational numbers. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] In this lesson students learn how to solve equations involving absolute value. Students can watch a video tutorial, explore guided notes and attempt practice problems.

Practice solving equations with rational numbers in them. Read the interactive quiz rules and then click on the "Begin" ticket. If you answer incorrectly you get one more chance to try again then you are told the correct answer. See how...

An explanation on how to solve fractions in rational equations which mentions what to do when extraneous solutions occur when solving.

A set of more difficult exercises on rational functions, complete with solutions. Asks for students to find the asymptotes of the equations given and to sketch the function.

[Free Registration/Login Required] By the end of the lesson, students will classify numbers into number families to help understand how to distinguish the difference between rational and irrational numbers. Students will demonstrate this...
