ANSWER

The discriminant is 49.

EXPLANATION

The given quadratic equation is:

$0 =2{x}^(2) + 3x - 5$

We can rewrite this as

$2{x}^(2) + 3x - 5 = 0$

Comparing this to

$a{x}^(2) + bx + c = 0$

We have a=2,b=3, c=-5.

The discriminant is given by:

$D = {b}^(2) - 4ac$

We plug in the values to get:

$D = {3}^(2) - 4(2)( - 5)$

D =9 + 40

D = 49
