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
