This isn't really a HW question, so I am posting it here. Hopefully someone will be able to help me, and I'm sure many of you will roll your eyes... I want to return one of my new calculators, but I'm not sure which one I should keep. I own the Casio FX-115ES and Sharp ELW516B, both unopened.

My question is, can either of these find the roots of a polynomial to the nth degree? For example, 5x^7-4x^5+11x. And can either of them find complex solutions?

Thank you for your time.

I recommend you consult the user's guides. If you don't want to open the boxes to get the guides out, there is a guide for the casio here:

I was unable to find a guide for the sharp EL W516B but reviews indicate that it can solve algebraic equations.
