This is my Quadratic Equation Solver. Instructions: 1. Use the QUAD program to start the program. 2. Input what A is when "A:" appears. 3. Input what B is when "B:" appears. 4. Input what C is when "C:" appears. 5. Watch as the program gets the answer. 6. If the program says "Could Not Find Valid Pairs. Using Quadratic Formula.", push enter... 6. (cont.) ...and watch it use the quadratic formula step-by-step. 7. Every program is needed to make the program work. Notes: 1. Bigger numbers will cause the program to take a while to solve. If you are patient, it will give an answer. 2. What still needs to be put in is shown at the top. 3. You cannot put in a zero for A, as that is already factored. 4. You cannot put in a zero for C, as you can just pull out an X for the answer. 5. Sometimes, the program, when using the quadratic formula, will have some of it pushed off to the side. 5. (cont.) This is normal and should be expected when using number greater then 10 (Something I am working on to fix). How it works: This program puts what you had put in for A, B and C into the standard AX^2+BX+C, quadratic format, and attempts to put it in A(Bx+C)(DX+E), factored format (Note that the A, B and C in the quadratic format while be different from the A, B and C in the factored format). If the program can't change from quadratic format to factored format, it will use the quadratic formula -B +/- sqrt(B^2- 4AC) ----------------------- 2A This will then show you the quadratic formula, step-by-step (Refer to Note 5 for additional information). The quadratic formula supports imaginary numbers andwill simplify the radical for you, all that needs to be done is to take the greatest common factor out (Something I am working on to implement).
