2^x*2^(x+1)=4^(x^2+x)
\n" ); document.write( "------------
\n" ); document.write( "2^(2x+1) = 2^(2x^2+2x)
\n" ); document.write( "------
\n" ); document.write( "2x+1 = 2x^2 + 2x
\n" ); document.write( "2x^2 = 1
\n" ); document.write( "x^2 = 1/2
\n" ); document.write( "x = sqrt(1/2) or x = -sqrt(1/2)
\n" ); document.write( "-------------------------------
