Adding Rational and Subtracting Expressions Example 3

This video focuses on rational expressions and completes Sal's lecture series on working with and solving this particular type of equation. Its length would be ideal for a computer lab visit or homework assignment (in conjunction with a...

Many times budding algebrists are fine when plugging specific numbers into expressions, but less certain when the range of acceptable values is undetermined. This detailed presentation helps the class move from the point value to...

Provide your algebra class with some review of rational expressions in this video. Sal uses several sample problems to show viewers the process, and his explanations are clear and easy to understand.

Extending his asymptotes lesson from the previous video, Sal shows viewers another example of graphing rational functions. This video is shorter than the previous one and could be shown in a single class session.

Evaluating expressions require two things- parentheses and PEMDAS. The video starts with an emphasis on using parentheses to plug in your variables. Once you have everything plugged in, PEMDAS will get your mathematicians to the correct...

Sal shows viewers how to solve rational expressions in this video, which would be an excellent resource for your lecture (or review session) in an algebra class. Those who have a hard time with rational expressions and those who have...

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....

Can you tell, algebraically, if three lines are parallel? In this video, Sal demonstrates how to rewrite linear equations in slope-intercept form and compare the slope of each line.
