Many physical and mathematical problems are in the form of quadratic equations. In mathematics, quadratic equations are used to solve a variety of real-life problems. In this sub-topic, we will learn about real-life applications of quadratic equation and we will understand the importance of quadratic equations using some practical examples.

To solve word problems, we follow the following steps.

Step 1: Read the problem carefully and draw diagram whenever possible.
Step 2: List all of the unknown numerical quantities involving in the problem and call it any letters such as p, q, x, y, z, etc.
Step 3: Using information given in the wording of the problem, set up a word equation that contains words as well as numbers.
Step 4: Solve the equation for the variable.
