In this lesson I will teach you how to solve rational equations. This is a big topic and requires many skills so if you find yourself struggling in any area do the smart thing and review/improve your weaknesses. Ok as you may already know the term “rational” implies fraction so this lesson is really about solving equations with fractions composed of variables and polynomials. One of things I will be teaching you in the lesson is how to clear all the fractions in a rational equation. This step however can cause the resulting new equation to form extraneous (extra) solutions. As such all the solutions we get need to be verified and checked- this is not an optional step. Like I said solving rational equations can be pretty involved so take your time and watch the lesson as much as you need to. Of course take excellent notes and practice is a must.
