The video tutorial explains how to solve an equation with rational expressions by eliminating denominators, simplifying the equation, and solving the resulting quadratic equation. It emphasizes the importance of verifying solutions to ensure they are not extraneous by checking that they do not make any denominators zero.

What is the first step suggested to handle the equation with rational expressions?

• Subtract a constant from both sides

• Divide both sides by a variable

• Multiply both sides by a common denominator

• Add a constant to both sides
