    You can use any method that is valid, includig the quadratic equation when it applies.

    Taking approximation if available

    if you're equil constant is smaller than 10^-5 or if the percent error is like 5%, then it's ok

    i forget how to calculate % error but just stick to 10^-5 and leave X out of your calculations
