Question

find the discriminate of the fo
following 2x (2)+x-4=0


please help me ​

Answer 1

Answer:

Here, a = 2

b = 1

c = - 4

$discriminant \: d = {b}^{2} - 4ac \\ d \: = {1}^{2} - 4(2)( - 4) \\ = 1 + 32 \\ = 33$

Answer 2

Answer :

Discriminant = 33

Step-by-step explanation :

Given quadratic equation,

2x² + x - 4 = 0

It is of the form ax² + bx + c = 0

a = 2, b = 1, c = -4

Discriminant is given by,

$\boxed{D=b^2-4ac}$

 $D=1^2-4(2)(-4) \\ D=1+32\\D=33$
