Re write
\n" ); document.write( "log(x-2)9=2
\n" ); document.write( "using exponents as
\n" ); document.write( "(x-2)^2 = 9
\n" ); document.write( "take a square root to get
\n" ); document.write( "x-2 = +3 or -3
\n" ); document.write( "x = 5 or x = -1.
\n" ); document.write( "However, we can't use -1, so the only answer is
\n" ); document.write( "x = 5. \n" ); document.write( "

\n" );
