In this lesson, you'll learn how to solve equations that are quadratic in form. By using the strategy of doubling the exponent on the first term, you can make an equation look like a quadratic equation, and then factor it to solve for a variable. The lesson uses an example equation of rational exponents to demonstrate the process of substitution, factoring, and back substitution. The lesson also emphasizes the importance of checking solutions, and provides an alternative method to solve the same equation.
