Project 3 A 1. The two solutions of a quadratic equation yax? + bx + c can be found using the quadratic formula: solutions - - + the square root of (b? - 4ac) 2a and solution2 = -b- the square root of (b 4ac) 2a Write a complete C++ program that ask the user to enter values for a, b and e, all on one line from the keyboard and output the values of solution, and solution2 Consider the following. Discriminant = b2 - 4ac, if discriminant >0 we have 2 real solutions, discriminant multiplication, addition, subtraction, / => division, => modulus, enter two numbers numb1, numb2 and a character that represents one of the 5 arithmetic operators (+. 96). Print an error message if the character is not one of the defined operators. Check division by zero 3 Crazy Al's Computer Emporium is a retail seller of home computers.
