x^2+14x+c\r\n" );
document.write( "\r\n" );
document.write( "1. The coefficient of x is 14.\r\n" );
document.write( "2. Multiply that coeficient 14, by .  Get 7\r\n" );
document.write( "3. Square 7. Get 49\r\n" );
document.write( "\r\n" );
document.write( "That's it.\r\n" );
document.write( "\r\n" );
document.write( "x^2+14x+c then becomes x^2+14x+49 which factors as (x+7)(x+7)\r\n" );
document.write( "which can then be written as (x+7)^2, which is the square of a\r\n" );
document.write( "binomial.\r\n" );
