What is the discriminant of the quadratic equation 0=2x^2 + 3x -5? 0-37 -31 0 43 049​

Discriminant = b²-4ac

from 2x²+3x-5=0

a = 2 b = 3 and c = -5

Discriminant = 3² - 4(2)(-5)

= 9+40

= 49

Discriminant = 49

Ans = 49

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
