I'm learning quadratic equations
I need practice solving them. I'm writing a spreadsheet so that I can get the correct answer.
I'll use this spreadsheet to make problems with answers for me to practice on
My spreadsheet can solve for x if a, b, and c are entered
I'd like to
solve a if x, b, and c are entered
solve b if x, a, and c are entered
solve c if x, a, and b are entered
The cells in purple are what I need
I just figured out that my spreadsheet has a bug.
I don't know how to take the square root of a negative number
The cell in question is p15
On the other stuff, it may not be possible. That's even better because my teacher won't ask these questions. (find c if x = 17)
