You need to tell them they can go into the settings and switch from real to a+bi and then the calculator will give imaginary roots.

Do you know how to reset it also?

[@khansher88]

Here is how I reset it: In the Equation menu, press F2 for Polynomial. The next screen will say "Data Exists In Memory". Select the degree by pressing F1 for second degree. On the next screen, press F2. It'll ask you "Delete Coefficients?". Press F1 for Yes. The screen should now say "No Data In Memory".

Just press the delete button. Usually F2, F6 is to delete all.
