Ahoy user !!
Here is ur answer --
ʀɑtiѳɳɑʆizɛ ......
2+3√5 / 2-3√5
= ( 2+3√5 / 2-3√5 ) * ( 2+3√5 / 2+3√5 )
= (2+3√5)^2 / (2)^2 - (3√5)^2
= (2)^2 + (3√5)^2 + 2*2*3√5 / 4-40
= 4+40+12√5 / -36
= 44+12√5 / -36
= 4 (11+3√5) / -36
= 11+3√5 / -9
= - ( 11+3√5 ) / 9
= - 11 - 3√5 / 9
HOPE IT IS HELPFUL.....☺
