    This lesson shows another example of how to solve an equation that looks and acts like a quadratic equation even though it has a degree other than 2. In this case, the degree is 2/3. It is always necessary for the highest power be twice as big as the middle power. All steps involved in converting the equation to a quadratic equation, solving, and checking are shown and explained.
