Problem $2$: Quadratic Equation

Develop a method named quadraticEquation that when given integers: $a,b,c$ and $x,$ describing a quadratic equation of the form:

$y=a{x}^2+bx+c,$ calculates and returns the value of $y.$

The rubric we will use to grade this method is:

The method has a correct header $($parameters and return type$)$

The method has a correct method body

There are at least two examples of calling the method with different arguments, commented with their expected values
