    how to apply quadratic formula to this

    2^{2x}-4^x\sinh{x}-1=0

    How might I apply the quadratic equation to this so as to solve for x?

    Or how might I solve for x via any method?


    Thanks

    Step in the right direction

    Add 1 to both sides, translate sinhx into exponential form, take the natural logarithm of both sides, then continue from there.
