Write a quadratic calculator in C++for the expression: a x2 + bxc 0 Declare variables a, b, c. Choose arbitrary values for these variable. Make sure that a is not zero and that the expresion inside the root is positive or zero to avoid working with imaginary numbers. 1. 2. Find the two roots: x1 and x2 using the usual quadratic formula: 2a 3. As an example, if a-1, b-2, and c-1, you must display the result using the following form with each number showing 2 fractional digits: 1 x2.00 2.00 x+1.00 x-1.00) (x--1.00) Note that because the roots in this example are negative (-1 and -1), the resulting factorization shows double negative signs. This is fine for the purposes of this assignment. 5. Find the maximum/minimum point using the formula: display the result using that format (with parenthesis as shown above) and also with each number showing 2 fractional digits. 6. You must add comments to the code. The evaluation rubric includes: logic and code correctness, formatting (proper use of vertical alignment of C++ code), and explanation of steps (comments)
