\n" ); document.write( "\n" ); document.write( "One look at this equation is enough to see that it has no solutions in real numbers.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Indeed,  for any real value of  x,   \"2%5E%282x-3%29\"  is less than  \"2%5E%282x-2%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So,  the difference  \"2%5E%282x-3%29\" - \"2%5E%282x-2%29\"  is always negative.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "When you subtract  1  from this negative number,  you get negative number lesser than  -1.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Thus,  left side of the equation can not be equal to zero.\r
