Answer:

discriminant:  4; number of real roots:  2

Step-by-step explanation:

The coefficients a, b and c of this quadratic are {-3, -2, 0}.

Thus, the discriminant b^2 - 4ac is (-2)^2 - 4(-3)(0), or 4.

Because the discriminant is positive, this quadratic has two real, unequal roots.

-3p^2 - 2p can be factored as follows:  -p(3p + 2).  If we set this expression equal to zero, we can find the roots:  {-2/3, 0}
