What condition on the discriminant gives two equal real roots?

The discriminant must equal exactly zero, D=0, for the quadratic equation to have two equal real roots.

What is the difference between the condition for equal roots and the condition for real roots?

Equal roots require D to equal exactly zero. Real roots require D to be greater than or equal to zero, which includes both the case of two distinct real roots (D greater than 0) and two equal real roots (D equal to 0).
