V2x2 – 5x + V2 = 0 ?
(A) - 5
(B) 17
(C) 2
(D) 2v2 - 5

please give answer fast​

Answer 1

Answer:

⇒ The given quadratic equation is 2x

2

−5x+3=0, comparing it with ax

2

+bx+c=0

⇒ We get, a=2,b=−5 and c=3

⇒ D=b

2

−4ac

=(−5)

2

−4(2)(3)

=25−24

=1

∴ Discriminant of given quadratic equation is 1
