2.6.3 Solving Fancy Quadratics

Question 1

fancy quadratics

Answer 1

• Frequently, an equation that appears to be of higher degree than a squared term can be rewritten so that your quadratic techniques allow you to solve it.
• Be creative with your use of variables. Look for ways to use them so that you can see your equation as a quadratic and use all your tools.
• Remember that whenever you solve an equation by substituting in a new variable, you must replace that variable when you have found its solution. At that point, you reinsert the original variable and solve for its values from this much simplified equation.
