You can do it the same way people did it before calculators were invented. Just use the quadratic formula: http://en.wikipedia.org/wiki/Quadratic_formula, and let the calculator handle the arithmetic. Some sophisticated calculators have generalized equation solvers that can handle equations much more complicated than the quadratic, but the fx-82 isn't one of them.

It is most likely that the angle unit is not set to correspond to the angle unit you are using in your problems. If your problems call for angle unit in degrees, set the calculator to do its calculations in degrees. If your problems require the radian angle unit, set your calculator accordingly.

There should be key marked [Y to the x] or [^]. If exponent is negative use the change sign key (-) not the MINUS sign.You will have to use the [^] key if you calculate roots of order higher than 3. Example 7th root of 353 =(353)[^](1/7)
