x^2+(a-b) x+(1-a-b)=0

, where

a, b \in R

, then the values of

a

for which equation has unequal roots for all values of

b

, is given by

View answer and explanation

Correct option: B

a > 1

Option B (

a > 1

) is correct because the discriminant of the quadratic in

b

must be negative to ensure unequal roots for all

b
