A) \[(-\infty ,1)\cup (6,\infty )\]
B) \[[6,1]\]
C) \[(1,6)\]
D) \[(-\infty ,1)\cup (7,\infty )\]
Correct Answer: A
Solution :
(a): For all greater than inequalities of the type, \[\left( x-a \right)\left( x-b \right)>0\]; \[a<b\] the solution is, \[x\in \left( -\infty ,a \right)\cup \left( b,\infty \right)\]; Since here \[a=1,b=6,\therefore \] the answer is \[x\in \left( -\infty ,1 \right)\cup \left( 6,\infty \right)\]You need to login to perform this action.
