A) \[|b|\le 6a\]
B) \[\left| b \right|\ge 6a\]
C) \[\left| b \right|=6a\]
D) None of these
Correct Answer: B
Solution :
[b] Let roots are \[\alpha \And \alpha +2\] \[\left( \alpha \ge 2 \right)\] \[\therefore \alpha +\alpha +2=-\frac{b}{a}\ge 6;\] \[i.e.\text{ }\left| b \right|\ge 6a\]You need to login to perform this action.
