Heres a program I made (i just learned turing today) for solving quadratic equations in math. Just enter the a, b, and c values and itll give u the roots. (y=ax**2+bx+[b]c[/b WARNING!!!-THE PROGRAM MAY HAVE AN ERROR IF THERE ARE NO REAL ROOTS |

don't you mean
because otherwise (sqrt(e)) the program will crash. its a good start, but now you should try to encorporate all of the roots. Its not that hard. Here's a hit
and here you go - squareroot part becomes possitive, you just got to keep in mind that you have to add in "i" later on (but flagi is marked as true to remind you) |

I had lots of stuff on my TI83.. you know how you used to have to do dozens of the same problems over and over with different numbers? yeah - just solve once for the variable values instead, and write down the function in TI  |
