Staff Review
This lesson explains how to set up and solve equations that look and act like quadratic equations but have a higher exponent than 2. The substitution and all steps involved in solving are shown and explained. Also, you will learn to recognize situations where this method applies, such as ay^6 + by^3 + c = 0 or a(x + 1)^2 + b(x + 1) + c = 0. It is also important to check your solutions.
