Solving a Polynomial Using Factoring by Grouping

The video tutorial covers factoring by grouping, focusing on equations with four terms. It explains how to group terms, factor out the greatest common factor (GCF), and apply the zero product property to solve equations. The tutorial also introduces the square root method for solving equations, including rationalizing the denominator to find solutions.

Describe the steps taken to solve the equation using the square root method.

What are the final answers obtained after rationalizing the denominator in the example?
