i looked at examples and it works....

do we look for solutions of the equation a^2 -a = kmn , for some k in Z( that is, other than 0 and 1)?

help!

that implies... bn(1-bn) = abmn = 0...

i looked at " am +bn =1" a hundred times before posting this question....but it flashed just now! thanks a ton!
