Extraneous Solutions

This task gives geometry learners practice in solving radical equations in one variable and zeros in extraneous solutions.

Pupils learn to solve square root equations and rationalize denominators. Problems include those with extraneous solutions. 

In this solving equations worksheet, students solve forty-four algebraic equations for real and imaginary solutions. Types of equations include higher degress polynomials, rational equationals, radical equations, and square roots inside...

This practice worksheet includes simple radical equations, and some quadratic equations that can be solved by the square root method. There is good practice here in checking the solutions, and a few graphing problems. 

There might be an extra solution. Pupils discover that the process of solving a radical equation is the same general process of solving any equation. They find out that in some instances, an extraneous solution occurs. Individuals then...

Determine a solution through accurate graphs. Using 2 examples, the narrator walks viewers through the steps to graph a system of linear equations to find the solution. 

After correcting the last problem in his previous video, Sal explains how to graph quadratic functions. Those with difficulty graphing algebraic functions will find Sal's instruction and easygoing manner a welcome change from staring at...

You've got some algebraic fractions in an equation and their denominators are all different. Well, first you need to strategize. Then find the excluded values that make your denominator equal zero because we know the denominator cannot...

High schoolers generate the equation of a polynomial given its roots and the end behavior of the function. They need to apply theorems concerning the multiplicity of roots, conjugates of irrational or imaginary roots to find a...
