\r\n" );
document.write( "They ask you to solve this quadratic equation\r\n" );
document.write( "\r\n" );
document.write( "150 = \"-3q%5E2+%2B+150q\"\r\n" );
document.write( "\r\n" );
document.write( "for q. It is the same as quadratic equation \r\n" );
document.write( "\r\n" );
document.write( "\"3q%5E2+-+150q+%2B+150\" = \"0\".\r\n" );
document.write( "\r\n" );
document.write( "To solve it, divide both sides by 3. It is your first step. You will get an equivalent equation\r\n" );
document.write( "\r\n" );
document.write( "\"q%5E2+-+50q+%2B+50\" = \"0\".\r\n" );
document.write( "\r\n" );
document.write( "Now apply the quadratic formula. You will get\r\n" );
document.write( "\r\n" );
document.write( "q = \"%2850+%2B-+sqrt%2850%5E2+-+4%2A50%29%29%2F2\" = \"%2850+%2B-+sqrt%282300%29%29%2F2\" = \"%2850+%2B-+47.958%29%2F2\" = . . . \r\n" );
