Let x be one number and y another. Then x-y = 16. Substitute y in terms of x into sum: x+(x-16) or 2x-16. Do the same with the product: x(x-16) = x^2-16x. To use a generally applicable method take the derivative of the product: 2x-16, and set equal to zero: 2x-16 = 0 or x = 8. As quadratics have a single extreme point this is sufficient to continue. Now the two numbers are: 8 and -8. Good day. \n" ); document.write( "
