1. A one-variable quadratic expression is an arithmetic
expression of the form ax2 + + bx c, where a,
b, and c are some fixed numbers (called the coefficients) and x is a
variable that can take on different values. Specify, design, and implement a
class that can store information about a quadratic expression. The constructor
should set all three coefficients to zero, and another method should allow you
to change these coefficients. There should be accessor methods to retrieve the
current values of the coefficients. There should also be a method to allow you
to evaluate the quadratic

to evaluate the quadratic expression at a particular value of x (i.e.,
the method has one parameter x and returns the value of the expression ax2
+ + bx c ).
Also write the following static methods to perform these
indicated operations:
Notice that the first argument of the scale method is a
double number (rather than a quadratic expression). For example, this allows
the method activation Quadratic.scale(3.14, q) where q is a quadratic
expression.
