We can solve quadratic equations by factorization, completing square and using quadratic formula. After practicing each method, you will be able to choose the method suitable for the given equation. In this article, we will learn the use of quadratic formula to solve quadratic equations.

To solve any given quadratic equation, we can use quadratic formula:

Let's solve one quadratic equation using Quadratic Formula. Suppose we have quadratic equation

By comparing this quadratic equation with the general quadratic equation , we get and

Putting the values of a, b and c in the quadratic formula we get,

And,

And,

Similarly, we can use quadratic formula to solve any given quadratic equation.

We can check if the given number is divisible by 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11 through divisibility tests. Each test is easy to perform on a given number except divisibility test of 7 which is harder as comparing to others. Go through the files and learn different divisibility tests. They can really help you in doing different calculations quickly.
