how do you use the quadratic formula on a TI-83 calculator? I'm in algebra 1!
To use the quadratic formula on a TI-83 calculator, follow these steps:
1. Enter the coefficients of the quadratic equation into the calculator. Let's say the equation is in the form of ax² + bx + c = 0, where a, b, and c are the coefficients.
2. Press the "MODE" button on your calculator.
3. Use the arrow keys to navigate to the "a+bi" mode under the "Real" header and press "ENTER" to select it. This will allow the calculator to display complex roots, if any.
4. Press the "PROGRAM" button on your calculator.
5. Scroll down and select the "QUADFORM" program option. Press "ENTER" to select it.
6. Once you have selected "QUADFORM," you will see a screen prompting you to enter the values of a, b, and c. Type in the appropriate coefficients and press "ENTER" after each value.
7. The calculator will then display the roots of the quadratic equation, either as real or complex numbers.
By following these steps, you can use the quadratic formula program on your TI-83 calculator to find the roots of a quadratic equation.
