Aratati ca fractia 2n+1 supra 3n+2 este ireductibila oricare ar fi n e N

If p is a prime number and p es a divisor of 2n+1 and 3n+2, so p algo is a divisor of 6n+3 and 6n+4, so p is a divisor of (6n+4 - (6n+3)) = 1, dont exist a prime that is divisor of 2n+1 ans 3n+2, so the fraction is irreductible
