A) - 4, 1
B) 4, - 1
C) 2, \[\sqrt{3}\]
D) \[-2,\,\,-\sqrt{3}\]
Correct Answer: A
Solution :
One root is \[2+\sqrt{3}\], then second root must be \[2-\sqrt{3}.\] Þ Sum of roots \[=-p=[2+\sqrt{3}+2-\sqrt{3}]=4\]Þ p = - 4 and product of roots \[=q=(2+\sqrt{3})(2-\sqrt{3}]=4-3=1\] Þ \[(p,q)=(-4,\,\,1)\].You need to login to perform this action.
