2nd class combinations

From how many elements you can create 4560 combinations of the second class?

Correct result:

n =  96


(n2)=n(n1)2=4560;n>0 n2n9120=0  a=1;b=1;c=9120 D=b24ac=1241(9120)=36481 D>0  n1,2=b±D2a=1±364812 n1,2=1±1912 n1,2=0.5±95.5 n1=96 n2=95   Factored form of the equation:  (n96)(n+95)=0   n>0n=96
