From we can see that , , and

Start with the discriminant formula.

Plug in , , and

Square to get

Multiply to get

Rewrite as

Add to to get

So the discriminant is

Since the discriminant is greater than zero, this means that there are two real solutions. These solutions are distinct (ie different from one another).
