Algebra.Com's Answer #509714 by richard1234(7193)![]() ![]() You can put this solution on YOUR website! x^2 - x = x(x-1). Either x or x-1 is divisible by 2, so x^2 - x is divisible by 2 (for integer x).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "For integer x, x^3 is not necessarily divisible by 3. \n" ); document.write( " |
