Question

Find the value of discriminant 5x² + 6x + 11 = 0​

Answer 1

Step-by-step explanation:

Correct option is

A

16

The given equation is 5x

2

−6x+1=0

General form of quadratic equation is given by ax

2

+bx+c=0

Comparing equation (i) with (ii) we have,

a=5,b=−6,c=1

The discriminant D is given by

D=b

2

−4ac=(−6)

2

−4(5)(1)=36−20=16

∴ Discriminant value is D=16.
