# Python Solve Quadratic Equation

In this snippet, we will learn how to calculate the area of a triangle in Python.

## Formula

Let's see the formula:

```
ax2 + bx + c = 0
Here a, b and c are real numbers and a ≠ 0.
```

## Example

Now let's see an example:

```
import cmath
a = 1
b = 4
c = 9
d = (b**2) - (4*a*c)
sol1 = (-b-cmath.sqrt(d))/(2*a)
sol2 = (-b+cmath.sqrt(d))/(2*a)
print('The solution are: {0} and {1}'.format(sol1,sol2))
```

The output:

`The solution are: (-2-2.23606797749979j) and (-2+2.23606797749979j)`

You can also run the program in our IDE.
