\r\n" );
document.write( "Let x = THE NUMBER OF DAYS TAKEN BY A AND B WORKING TOGETHER TO DO THE WORK.\r\n" );
document.write( "\r\n" );
document.write( "The the number of days for A to do the job working alone is (x+8), and \r\n" );

document.write( "To solve it, multiply everything by x*(x+8)*(x+18). You will get\r\n" );
document.write( "\r\n" );
document.write( "x*(x+18) + x*(x+8) = (x+8)*(x+18).\r\n" );

document.write( "\"x%5E2+%2B+18x+%2B+x%5E2+%2B+8x\" = \"x%5E2+%2B+8x+%2B+18x+%2B+144\",  or\r\n" );
document.write( "\r\n" );
document.write( "\"x%5E2\" = 144.\r\n" );
