Solving quadratic and other nonlinear equations

By the end you’ll be able to

• Solve quadratic equations in one variable by factoring, completing the square, applying the square root property, or using the quadratic formula.
• Determine the number and nature of solutions to a quadratic equation from its structure, equivalent form, or discriminant when appropriate.
• Solve equations that can be rewritten as quadratics, such as polynomial equations in higher powers with substitution or structure-based factoring.
