;
Solve when: "n = 3" ;
Rewrite the expression; substituting "3" for all values of "n" ; as follows:
→
;
The "6" cancels out to "2" ; & the "3" cancels out to "1" ;
→ {since: " {6 ÷ 3 = 2}" ; and since: " {2 ÷ 2 = 1}" .

→ Since the "denominator" is "1" ; and any value, divided by "1"; results in that original value; we can eliminate the denominator.
→ Now, we can rewrite the expression as:

→ " 2(3² + 2)" ;
= 2(9 + 2) ;
= 2(11) ;
= " 22 " .

Answer:Answer is option C : [ + 3x + 3 ] =0
Note: None of options matches with given question.
instead of "-3" , there should be "-".
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>
