\"0.25%5Ex%2Bcross%28-0.5%2B0.5%29=2%2B0.5\" Add 0.5 to both sides
\n" ); document.write( "\"log%280.25%5Ex%29=log%282.5%29\"Take the log base 0.25 of both sides
\n" ); document.write( "\"x=log%282.5%29\"
\n" ); document.write( "\"x=log%282.5%29%2Flog%280.25%29\"
\n" ); document.write( "\"x=-0.66096\"

\n" ); document.write( "\"0.25%5E%28-0.66096%29-0.5=2\"
\n" ); document.write( "\"2.4999-.5=2\"
\n" ); document.write( "\"1.9999=2\" which is really close and it's only off due to roundoff errors so it works
\n" ); document.write( " \n" ); document.write( "
