Describing and Solving for the Zeros Using Difference of Two Squares

The video tutorial covers the process of factoring equations, starting with identifying the greatest common factor (GCF) and setting equations to zero. It explores the concept of taking the fourth root and further factoring using the difference of squares. The tutorial then applies the zero product property to solve equations, leading to the identification of real and complex roots. The video concludes with a summary of the solutions found, including three real rational roots and two complex roots.

Explain the difference between the roots ±3 and ±3i.

What are the three real rational roots obtained from the equation?
