Question

Write a program in C++ to find the solution to a polynomial, given the coefficients A, B, C in the equation below.

Ax^2 + Bx + C = 0

Use the quadratic equation, there should be 2 solutions. The solutions should have 2 decimal places

Sample output is given below.

Enter coefficient A: 1

Enter coefficient B: -1

Enter coefficient C: -6

The two solutions to this equation are 3.00 and -2.00
