    please use parenthesis so I can be sure of the order of operations there, as you have it i interpret that as


    e^2x-e^x-6 but if that was correct you wouldn't have included the 1 I dont think

    @OP: \Rightarrow e^{2x} = u^2.

    Surely the equation you intend is e^{2x} - 1 e^x - 6=0, in which case there ARE brackets: e^(2x).
