e^(2x)-2e^x+1 =0 Solve:
\n" ); document.write( "let u=e^x
\n" ); document.write( "u^2=e^(2x)
\n" ); document.write( "..
\n" ); document.write( "u^2-2u+1=0
\n" ); document.write( "(u-1)^2=0
\n" ); document.write( "u=1 (mult. 2)
\n" ); document.write( "u=e^x=1
\n" ); document.write( "x=0 \n" ); document.write( "

\n" );
