This is a quadratic equation, and it's already equal to zero, so you need to factor it. However, the fractions are pretty ugly here. It might help to get a common denominator of 1000 like this:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"0=%286%2F10%29h+-+%285%2F1000%29h%5E2\"
\n" ); document.write( "\"0=%286%2F10%29%2A%28100%2F100%29h+-%285%2F1000%29h%5E2\"
\n" ); document.write( "\"0=%28600h-5h%5E2%29%2F1000\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply both sides by 1000:
\n" ); document.write( "\"0=600h-5h%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Factor out the common factor of 5h:
\n" ); document.write( "\"0=5h%28120-h%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are two solutions:
\n" ); document.write( "5h=0
\n" ); document.write( "h=0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "120-h=0
\n" ); document.write( "120=h\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "R^2
\n" ); document.write( "
\n" );
