Let me tell you that it is a shame to go to the forum with such questions.

It is the same as asking pedestrians in the street how many is 2x2.

Factor when Possible
x^2+6X=0

Discriminant:
With the discriminant being a PERFECT SQUARE, then
Now that you have the discriminant, you can continue to solve using the quadratic equation formula, but since the binomial can be factored,
it's easier to do so to get the exact roots.
