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.
----- Dividing by GCF, 3 to make leading coefficient (), 1 ----- Halving b, or (), squaring it, and then adding to both sides -------- Taking square root of both sides OR OR
