Solving Rational Equations Concepts

The video tutorial explains how to solve a rational equation by identifying excluded values, finding the least common denominator, simplifying the equation, and solving for x. It emphasizes the importance of avoiding division by zero and demonstrates the process of clearing fractions using the least common denominator. The solution is verified by ensuring it is not one of the excluded values.

What is the first step in solving a rational equation?

• Identify the least common denominator

• Cross-multiply the fractions

• Identify values that make denominators zero

• Add fractions on both sides
