1- A quadratic equation for variable x is expressed as: ax2 + bx + c = 0, where a, b, and c are the coefficients. The two roots of a quadratic equation can be calculated using the following quadratic formula: -bb2-4ac 2a For example, the roots of x2 - 3x 40 are x 4 and x = -1 a) Write a C++ program to solve the quadratic equation. Compare your answer with the example above. b) What are the datatypes that should be used in the program to represent the formula's coefficients?
