Rationalising Factor

CBSE IX Maths Number System

I wanted to know why the rationalising factor of the equation $begin inline style fraction numerator 5 plus 2 square root of 3 over denominator 5 minus 2 square root of 3 end fraction end style$ is , instead of . This equation was in one of the video lessons, and I am a bit confused why addition is being used in the rationalising factor. Can I use as the rationalising factor?
