Step-by-step explanation:
Note: None of options matches with given question.
instead of "-3" , there should be "".
Here, First thing you have to observe the nature of roots.
∴ x = -+
i and x = -
-
∴ [ x+(-
i) ][ x+(
+
i) ]=0
∴ [ + x(
+
i)+ x(
-
i) + (
-
i)(
+
i) ]=0
∴ [ +
x +
ix +
x -
ix + (3-
i)(3+
i) ] =0
∴ [ + 3x + (
-
i)(
+
i) ] =0
∴ [ + 3x +
- (
i)(
i) ] =0
∴ [ + 3x +
- (
)
] =0
∴ [ + 3x +
+ (
) ] =0
∴ [ + 3x +
] =0
∴ [ + 3x + 3 ] =0
Thus, Answer is option C : <em>[ + 3x + 3 ] =0 </em>
