A one-variable quadratic expression is an arithmetic expression of the form axbx+c, where a, b, and c are some fixed numbers (called the coefficients) and x is a variable that can take on different values. Design and implement a class that can store information about a quadratic expression. The default constructor should set all three coefficients to zero, and another member function should allow you to change these coefficients. An overloaded constructor should also be able to
