I have a really quick question about if it is even possible to give a "plus or minus" notation within an equation, for example the quadratic formula discriminant:

(-b ± sqrt (b2 – 4 a c) / 2 a

I first thought perhaps:

-b + || - .....

However that threw up errors,

I also tried

-b +-.....

However it took the last "-" as a negative sign as opposed to plus or minus

any help would be appreciated

You have to remember that what you have there is actually two different formulas (although always presented as one). there is no native symbol in C or C++ to represent this. you could create a class to handle it if you wish.

Gotcha, thank you very much
