The values of '

a

' for which one root of the equation

x^{2}-(a+1) x+a^{2}+a-8=0

exceeds 2 and the other is lesser than 2 , are given by :

View answer and explanation

Correct option: C

 -2

Option C ( -2) is correct because the condition that one root exceeds 2 and the other is less than 2 implies

f(2) < 0

, which leads to the solution

a < -2
