You can put this solution on YOUR website!
Let e^x = a, and re-write.
\n" ); document.write( "a² - 7a + 12 = 0 -- We have a factorable quadratic
\n" ); document.write( "(a - 3)(a - 4) = 0
\n" ); document.write( "a = 3 or 4
\n" ); document.write( "e^x = 3 or 4
\n" ); document.write( "x = ln(3) or ln(4) \n" ); document.write( "

\n" );
