Solve basic rational equations and explain extraneous solutions

The video tutorial covers solving rational equations, focusing on identifying and handling extraneous solutions. It begins with an introduction to rational equations and a warmup exercise using the least common denominator. The tutorial then explores handling variables in denominators, emphasizing the importance of removing them and explaining cross multiplication. Finally, it delves into extraneous solutions, illustrating how they arise and how to test for them, ensuring solutions satisfy the original equation.
