Has somebody made an app that you plug in numbers in the quadratic Formula an you get your 2 answers? I want it to make school easy. Thanks for your time.

Why would you want to do that? The Prime can solve quadratics without a program already.
E.g. Code: CAS.zeros('X²6*X+2') There are only 10 types of people in this world. Those who understand binary and those who don't.

You have also the builtin Explorer app.

If those don't work for you, this is a nice little exercise for you to program yourself.

I think the best tool Prime provides to solve polynomials is the command: proot.
I prefer proot for the following reasons
Example: Find roots for x^2+4x+5. Code: proot([1,4,5]) [(2,1) (2,1)] There are other useful commands in the Polynomial menu too. Such as solving for the coefficients instead of the roots. I recommend it.

Hello Subaru, Welcome! Don’t be afraid, there is no stupid question here, we are all here to help you, and as you see, there are plenty of answers, even if we all think that there is no need to program the quadratic formula.
