#### Answer

Discriminant: $36$;
Roots/solutions: Two rational numbers

#### Work Step by Step

Let us determine the discriminant of the quadratic equation $2x^2+6x=0$
which can be calculated as: $D=b^2-4ac=(6)^2-0=36$
This implies that $D$ represents a positive real number and a perfect square with solution of two unequal real numbers.
Therefore, the roots /solutions will be of Two rational numbers.
Hence, our answer is:
Discriminant: $36$;
Roots/solutions: Two rational numbers
