log(x+3)=log 2 - log (x-2)
\n" ); document.write( "------
\n" ); document.write( "log[(x+3) = log[2/(x-2)]
\n" ); document.write( "-------
\n" ); document.write( "x+3 = 2/(x-2)
\n" ); document.write( "(x-2)(x+3) = 2
\n" ); document.write( "----
\n" ); document.write( "x^2 + x -8 = 0
\n" ); document.write( "---
\n" ); document.write( "x = [-1 +-sqrt(1-4*-8)]/2
\n" ); document.write( "----
\n" ); document.write( "x = [-1 +- sqrt(33)]/2
\n" ); document.write( "---
\n" ); document.write( "x = (-1/2) + sqrt(33)/2
