\r\n" );
document.write( "Let x be one of the two numbers.\r\n" );
document.write( "Then the other number is  (32-x),  and the product of the two numbers is  \"x%2A%2832-x%29\" = \"-x%5E2+%2B+32x\".\r\n" );
document.write( "\r\n" );
document.write( "To answer the question, complete the square in the right side quadratic polynomial.\r\n" );
document.write( "\r\n" );
document.write( "\"x%2A%2832-x%29\" = \"-x%5E2+%2B+32x\" = \"-%28x-16%29%5E2+%2B+16%5E2\".\r\n" );
document.write( "\r\n" );
document.write( "Now, the right side has the maximum equal to  \"16%5E2\" = \"256\"  at  x = 16.\r\n" );
document.write( "For any other value of  x  the negative quadratic term in the right side of the expression makes it lesser.\r\n" );
document.write( "\r\n" );
document.write( "So, the maximum of the product of the numbers  x  and  (32-x)  is achieved at  x = 16  and it is  256.\r\n" );
