\n" ); document.write( "Here is one of many ways to solve the problem.

\n" ); document.write( "Since the two numbers add to 10, let them be (5+a) and (5-a).

\n" ); document.write( "The product of the two numbers is -16:

\n" ); document.write( "\"%285%2Ba%29%285-a%29=-16\"
\n" ); document.write( "\"25-a%5E2=-16\"
\n" ); document.write( "\"41=a%5E2\"
\n" ); document.write( "\"a=sqrt%2841%29\" or \"a=-sqrt%2841%29\"

\n" ); document.write( "ANSWERS: \"5%2Bsqrt%2841%29\" and \"5-sqrt%2841%29\"
