From the Pythagorean theorem,
\n" ); document.write( "\"A%5E2%2BB%5E2=H%5E2\"
\n" ); document.write( "\"x%5E2%2B15%5E2=%28x%2B5%29%5E2\"
\n" ); document.write( "Use the FOIL method to expand the right hand side...
\n" ); document.write( "\"x%5E2%2B225=x%5E2%2B5x%2B5x%2B25\"
\n" ); document.write( "\"x%5E2%2B225=x%5E2%2B10x%2B25\"
\n" ); document.write( "\"10x%2B25=225\"
\n" ); document.write( "Take it from there to solve for \"x\"
