\"a%2Asqrt%28b%5E2-c%29=5k\"
\n" ); document.write( "\"4%2Asqrt%287%5E2-c%29=5%2811%29\"
\n" ); document.write( "\"sqrt%2849-c%29=55%2F4\"Divide by both sides by \"4\"
\n" ); document.write( "\"49-c=%2855%2F4%29%5E2\"Square both sides
\n" ); document.write( "\"49-c=3025%2F16\"
\n" ); document.write( "\"c=784%2F16-3025%2F16\"Change 49 to a fraction with denominator of 16
\n" ); document.write( "\"c=-2241%2F16\"
\n" ); document.write( "
\n" );
