The instructor in this video (04:12) discusses how to solve rational equations using just one problem. He uses computer software for demonstration. The viewer may want to open the video to 'full screen' because the instructor has a lot of small writi...ng on a black screen.[more]

The instructor in this video (12:57) discusses how to solve rational equations. He uses computer software for demonstration. The viewer may want to open the video to 'full screen' because the instructor has a lot of small writing on a black screen.

The instructor in this video (04:08) discusses how to solve rational equations using another problem. Sl Khan shows how to multiply to remove the fractions to make solving easier. He uses computer software for demonstration. The viewer may want to op...en the video to 'full screen' because the instructor has a lot of small writing on a black screen.[more]

Sal Khan continues (04:31) his discussion about rational equations and how to solve them (in this case, using factoring). He uses computer software for demonstration. The viewer may want to open the video to 'full screen' because the instructor has a... lot of small writing on a black screen.[more]

In this video, the instructor goes through two examples of solving rational equations. He works through the problems step by step and writes out each step as he explains it. The instruction is quite clear and thorough, making this good practice for... these types of equations.[more]

Holes are missing points in the graph of a rational equation. A hole in a graph of a rational equation will occur when a value of x causes both the numerator and denominator to equal zero. An example is shown on an interactive white board. ( 1:25)

In this video, the instructor tells how to solve a rational equation. He goes through the steps necessary to solve the equation. He goes through step by step on a white board. The video would be best viewed full screen so it is easier to see the p...roblem.[more]

In this short lesson, the instructor shows how to solve a rational equation. He first factors and finds the common denominator. He shows each step on a white board so it is fairly easy to follow along. He does skip some steps at the end, assuming ...that the viewer knows how to solve for a variable.[more]

To solve rational expressions, or rational equations, solve for X
by first multiplying both sides by the lowest common denominator. A standardized test prep instructor explains how to solve rational expressions with examples on a whiteboard. Narrat...ors speech is shown as text on bottom of screen.[more]
