Major mistake when solving rational equations

The video tutorial explains how to solve rational equations by identifying and multiplying by the least common denominator (LCD). It covers multiple examples, including using inverse operations, cross multiplication, and factoring. The tutorial also highlights common mistakes students make, such as not checking for extraneous solutions, and provides tips for identifying the LCD in polynomial equations.
