Strategy for Choosing the Most Appropriate Method to Solve a Quadratic Equation
When solving a quadratic equation, the structure of the equation determines which of the available methods will be fastest and most efficient. Although the Quadratic Formula can solve any quadratic equation, it is not always the easiest approach. A three-step decision process helps select the best method:
Step 1. Try Factoring first. If the quadratic expression factors easily, this method is the quickest route to the solutions.
Step 2. Try the Square Root Property next. If the equation fits the form or , the Square Root Property provides a direct and efficient solution.
Step 3. Use the Quadratic Formula. If the equation does not factor easily and does not match the Square Root Property forms, the Quadratic Formula will always work.
Completing the square is not listed as a preferred solving method because most people find it cumbersome. However, the technique was used in general to derive the Quadratic Formula and also appears in other areas of algebra, so it remains an important skill even though it is rarely the most convenient choice for solving equations.
