Hate to do double threads but I felt this was a totally different issue that needed to be addressed. Here goes:

Code:

#include <iostream>
#include <cmath>
using namespace std;
float Quad(float x, float y, float z);
int main() {
float a;
float b;
float c;
float funcvarb;
cout << "\tQuadratic Formula is Fun!! (that's why this is doing it for you) "<< endl;
cout << "\t\tInput the coefficients to the quadratic equation!" << endl;
cout << "(A)X^2 input a please" ;
cin >> a;
cout << "\n(B)X input b please" ;
cin >> b;
cout << "\n(C) input c please" ;
cin >> c;
funcvarb = Quad(a, b, c);
cout << "X = " << funcvarb << endl;
cin.get();
return 0;
}
float Quad(float x, float y, float z) {
float plusanswer;
float minusanswer;
plusanswer = ((-y + sqrt((y*y) - 4(x)(z)))/2x)
minusanswer = ((-y - sqrt((y*y) - 4(x)(z)))/2x)
cin.get();
return (plusanswer, minusanswer);
}

I had the idea of making the Quadratic formula work...but you know how that goes. Also, I want to know if i can let it do imaginary by :

let sqrt(-1) = i

Something of that nature. Whatever. I just had a mere idea of how to implement this. Let me tell you the errors!

Basically the only thing is that it says i can't use 4 and 2 as a function because when i say

it assumes it's a function. How do I fix this? Much help is appreciated. I hope I have good structure and everything
