    Quadratic Formula Calculator and Solver

    The calculator on this page shows how the quadratic formula operates, but if you have access to a graphing calculator you should be able to solve quadratic equations, even ones with imaginary solutions.
    • Step 1) Most graphing calculators like the TI- 83 and others allow you to set the "Mode" to "a + bi" (Just click on 'mode' and select 'a+bi')
      • If you can set your calculator's mode to a + bi you should be able to even calculate imaginary solutions
    • The rest of the steps just involve typing in a,b and c. Make sure that you divide the entire numerator by 2a, just use parentheses
