e^x-15e^-x=2
\n" ); document.write( "Multiply by e^x
\n" ); document.write( "---
\n" ); document.write( "e^(2x) - 15 = 2e^x
\n" ); document.write( "e^(2x) - 2e^x - 15 = 0
\n" ); document.write( "(e^x - 5)*(e^x + 2) = 0
\n" ); document.write( "e^x = 5
\n" ); document.write( "x = ln(5)
\n" ); document.write( "------
\n" ); document.write( "Ignore e^x = -2
\n" ); document.write( " \n" ); document.write( "
