1. What is a Quadratic Formula?
The Quadratic Formula is used to solve quadratic equations, which are equations with a second-degree polynomial of the form ax2 + bx + c = 0
The quadratic formula can be used to find the two solutions of these equations, which are known as the roots.
The Quadratic Formula is expressed as
To use this formula, you must first know the values of a, b and c in your equation.
2. How to Use Quadratic Formula?
Let’s learn how to use the above quadratic formula.
Step 1: Check whether the given equation is quadratic or not.
Step 2: If it is a quadratic equation, compare it with the standard form ax2 + bx + c = 0 .
Step 3: Substitute the values of a, b and c in the quadratic formula.
Step 4: Calculate both roots of the given quadratic equation.
Take a look at the three examples below.
