%283n%5E2+%2B+2n%5E2+%2B+18n%29+%2F+6n%5E2+

%285n%5E2+%2B+18n%29+%2F+6n%5E2+
n%285n+%2B+18%29+%2F+6n%5E2+
cross%28n%29%285n+%2B+18%29+%2F+6n%5Ecross%282%29+
%285n+%2B+18%29+%2F+6n+
5n%2F6n+%2B+18%2F6n+
5cross%28n%29%2F6cross%28n%29+%2B+cross%2818%293%2Fcross%286%29n+
5%2F6+%2B+3%2Fn+
now, you can set expression equal to zero and calculate n
5%2F6+%2B+3%2Fn=0+
3%2Fn=-5%2F6+
3=-%285%2F6%29n+
-3%2F%285%2F6%29=n+
-3%2A6%2F5=n+
-18%2F5=n+
