E^2X+6E^X-27=0
\n" ); document.write( "-------------
\n" ); document.write( "Assuming the 1st exponent is 2x:
\n" ); document.write( "----
\n" ); document.write( "Sub y for e^x
\n" ); document.write( "----
\n" ); document.write( "y^2 + 6y - 27 = 0
\n" ); document.write( "(y+9)*(y-3) = 0
\n" ); document.write( "y = -9 --> e^x = -9 ***** not possible
\n" ); document.write( "=============
\n" ); document.write( "y = 3
\n" ); document.write( "e^x = 3
\n" ); document.write( "x = ln(3)
