The discriminant is zero. It tells you that there are two identical real roots to the equation.

#### Explanation:

If you have a quadratic equation of the form

The solution is

The discriminant

The discriminant "discriminates" the nature of the roots.

There are three possibilities.

- If
#Δ > 0# , there are**two separate**real roots. - If
#Δ = 0# , there are**two identical**real roots. - If
#Δ <0# , there are**no**real roots, but there are two complex roots.

Your equation is

This tells you that there are two identical real roots.

We can see this if we solve the equation.

There are two identical roots to the equation.
