Answer: D = -8

Step-by-step explanation:

Ohh okk so the discriminant basically helps find the number of solutions to a quadratic equation

If D(discriminant) is:

< 0 there are no solutions

= 0 there is one solution

> 0 there are two solutions

The discriminant is found using

b^2 - 4ac

Here a = 3

b = -4

c = 2

(-4)^2 - 4(3)(2)

16 - 24

-8
