a) 21
b) 12
c) 141
d) 5

D = 141

Step-by-step explanation:

The given quadratic equation is

.

It is required to find the value of the discriminant. The value of discriminant  of any quadratic equation is given by :

Here, a = 5, b = 9 and c = -3

On plugging all the values, we get :

So, the value of discriminant for y is 141.
