What is the discriminant of the quadratic equation 2x² - x - 3=0?
Tamiku [17]

The given quadratic equation is

2 {x}^{2}  - x - 3 = 0

comparing with

{ax}^{2}  + bx + c = 0

We get ,

a = 2 \\ b =  - 1 \\ c =  - 3

formula :

D =  {b}^{2}  - 4ac \\  \\ D =  {( - 1)}^{2}  - 4 \times 2 \times ( - 3) \\  \\ D = 1 - ( - 24) \\  \\D  = 1 + 24 \\  \\D  = 25.

Discriminant of given quadratic equation is 25 .

option (B) 25 ✔
