If you don't know how to complete a square, check out this website: https://www.mathsisfun.com/algebra/completing-square.html
However, if you're just stuck on this question, you can view my solution here:
We can complete the square by adding 2 to both sides.
x2+(2√3)x+3=2(x+√3)2=2
From this, we can tell:
r=√3s=2
The answer you seek is 2,
I hope this helped,
