# What is the quadratic formula used for?

##### 1 Answer

The quadratic formula is used to get the roots of a quadratic equation, if the roots exists at all.

We usually just perform factorization to get the roots of a quadratic equation. However, this is not always possible (especially when the roots are irrational)

The quadratic formula is

Example 1:

Using the quadratic formula, let's try to solve the same equation

Example 2:

Performing factorization is a little hard for this equation, so let's jump straight to using the quadratic formula
