Have you ever wondered if there is a way to make your calculator solve quadratic equations for you? Well, there is a fairly easy way to make your calculator do all the work for you.
Another program that I have put on Instructables is Heron's Formula.
Step 1: Getting Started
The first step is to press the program button on your calculator. Press the right arrow twice to get to new and select create new. Enter a name.
Now press program again and press the right arrow then press 2. To get letters, push the alhpa button. Now enter A,B,C and hit enter.
Step 2: The Equation
Refer to the second picture for the second part of the equation. It is just like the first part except for a couple things.
Step 3: Displaying Results
Step 4: Using the Program
Now push program and select the one you just made. Hit enter and type in the value of A. Then do this for B and C. Remember ax^2+bx+c=0. Example: x^2-3x+2=0; A=1, B=-3 (use negative sign if necessary), C=2. The bold numbers are the numbers that you would enter in your program. After you enter all three variables hit enter and you get your answer.
