\r\n" );
document.write( "For a quadratic to be factorable, the discriminant must be a perfect square.\r\n" );
document.write( "All perfect squares are non-negative, so we look at the square roots.\r\n" );
document.write( "\r\n" );
document.write( "1.____28  That is NOT because √28 = 5.291592622... not a real whole number.\r\n" );
document.write( "Not factorable, has real solutions. \r\n" );
document.write( "\r\n" );
document.write( "2.____225 That IS because √225 = 15, which is a real whole number. Factorable, has real rational solutions.\r\n" );
document.write( "\r\n" );
document.write( "3.____-36 That is NOT because √(-36) = 6i, an imaginary number, not a real whole number. Not factorable, no real solutions.\r\n" );
document.write( "\r\n" );
