\n" ); document.write( "Cross-multiply to get:
\n" ); document.write( "(x+1/x) = 3(x+1/x)
\n" ); document.write( "----
\n" ); document.write( "x + 1/x = 3x + 3(1/x)
\n" ); document.write( "--------
\n" ); document.write( "2x + 2(1/x) = 0
\n" ); document.write( "----
\n" ); document.write( "x + 1/x = 0
\n" ); document.write( "----
\n" ); document.write( "x^2 + 1 = 0
\n" ); document.write( "x = i or x = -i
