**Sympy** is a system for symbolic maths in python. It doesn't just compute, it also differentiates, integrates
and automates common calculus steps. It also has a great documentation page.

Let's first install it.

```
pip install sympy
```

The code from this video is listed below.

```
import sympy as sp
x = symbols('x')
f = x ** 2 + 4 * x - 16
sp.solve(f, x)
```
