A) \[-i\]
B) \[i\]
C) \[\sqrt{3}\]
D) \[\frac{\sqrt{3}}{2}\]
Correct Answer: A
Solution :
[a] One root of quadratic equation be \[\frac{-1+\sqrt{3}}{2}\] Other root of quadratic equation be \[\frac{-1-\sqrt{3}}{2}\] Sum\[=\frac{-1}{2}-\frac{1}{2}=-1\] Hence, option [a]is correct.You need to login to perform this action.
