A) 4
B) \[-4\]
C) 1
D) \[-\text{1}\]
Correct Answer: B
Solution :
Let first root [a] and second is\[(\beta )\]. \[\therefore \] Product of roots \[(\alpha \beta )=\frac{c}{a}=\frac{3}{1}\] So, \[\beta =1\] And sum of roots \[(\alpha +\beta )=-k\] \[-k=1+3=4\Rightarrow k=-\,\mathbf{4}\]You need to login to perform this action.
