Algebra 1 - Solving Radical Equations

| No Comments | No TrackBacks

In today's free Algebra 1 video, we are moving forward with radicals into Solving Radical Equations. A radical equation is an equation that contains a variable within a radical. As with the previous lessons on radicals, these can be a bit scary just seeing the equation for the first time. However, once you learn a few math tricks, you'll be solving radical equations in no time! You'll learn how to solve simple equations by squaring both sides and how to solve more complicated equations by either adding, subtracting, multiplying or dividing.  Best part is once you've solved the equation, you can check your work to make certain it is right by plugging in the answer. Checking your work becomes very useful when extraneous solutions are introduced. An extraneous solution is a number that is not a solution of the original equation.  This can happen when you square both sides of an equation. With Professor Burger's sense of humor and easy to understand teaching style in the 6 lectures on the video, you'll be solving radical equations like a mathematician.
