you divide both terms by 4 because its the common denominator so (12/4)+(4√5/4)= 3+√5
Though I am not very sure

12 and 4 are both divisible by 4 so just divide them by it.

If we consider the second fraction in 2 parts, as numerator and denominator, and expand the denominators only, what do we get?
