This WebMath site is a java program that will simplify a trig expression. This is a good site to use to check answers to problem sets. Read the site instructions carefully.

Factor the numerator and the denominator of a rational expression and cancel out common binomial terms. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Factor the numerator and the denominator of a rational expression and cancel out common monomial factors. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

This WebMath site provides links to tutorials and lessons in both Algebra I and II. Links to topics such as factoring, solving equations, polynomials, simplifying equations, graphing, and much more.

Learners explore the Pre-Calculus concept of rational expressions. The tutorial examines how to simplify rational expressions. The activity consists of examples and practice exercises with detailed solutions.

Use this site to learn how to simplify radicals, even when the radical is not a perfect square. These examples will be a guide to you in simplifying all kinds of radicals.

This question-response site gives information about simplifying an expression using conjugates. The Dr. first details the fundamentals of conjugates and then works several examples.

Get independent practice working with simplifying polynomials. Each incorrect response gets a text box explanation and another try. Correct responses are confirmed.

This site walks you step-by-step through simplifying an expression under a square root sign. Type your problem into the "math solver," and your answer, complete with a full description, is provided.

Example: Subtract and simplify (a-2)/(a+2) - (a-3)/(a^2+4a+4).

Example: Add and simplify 6/(2x^2-7) + (-3x-8)/(2x^2-7).

Example: Add and simplify x/(2x+1)(x-7) + 2x^2/(2x-3)(x-7).

The process of factoring and canceling is used to simplify, multiply, and divide rational expressions. Adding and subtracting rational expressions is also demonstrated, including finding common denominators.

Students learn about the concept of multiplying terms by exploring a tutorial. They can then test their knowledge by taking a ten question assessment that increases in difficulty as they correctly answer questions.
