Get 3 as a factor ..

Divide 11/3 by 2 and square it. And subtract it. So nothing changes. Hope you understand.

Now you know .. you can complete square like this..

There you got the answer.
I will tell you an easy way to remember square completing
Just divide the coefficient with x and put it in with the original x. Now subtract the remaining number with no variable by the square of the number inside the bracket which you have made a while ago.
Ex :-
Divide 4 by 2 and put inside.
. Done.. now you have 8 remaining.
