Question

Discriminant D = ...... for the quadratic equation 5x2–6x+1=0,select a proper option (a), (b), (c) or (d) from given options so that the statement becomes correct.
(a) 16
(b) √56
(c) 4
(d) 56

Answer 1

Option A is correct
The Discriminant of the quadratic equation is 16
Hope this helps you. ....✌

Answer 2

Option (a) is correct.

Explanation :

Compare given Quadratic equation

5x²-6x+1= 0 with ax²+bx+c = 0 ,we

get,

a = 5 , b = -6 , c = 1

Discreminant ( D ) = b² - 4ac

= (-6)² - 4×5×1

= 36 - 20

= 16

Therefore ,

D = 16
