## Quadratic Formula Calculator

## Calculator Use

When \( b^2 - 4ac = 0 \) there is one real root.

When \( b^2 - 4ac > 0 \) there are two real roots.

When \( b^2 - 4ac < 0 \) there are two complex roots.

## Quadratic Formula:

is used to solve quadratic equations where a ≠ 0 (polynomials with an order of 2)

## Examples using the quadratic formula

The discriminant \( b^2 - 4ac > 0 \) so, there are two real roots.

Simplify fractions and/or signs:

The discriminant \( b^2 - 4ac < 0 \) so, there are two complex roots.

- 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.
