Create a method delta() that takes three integer values, a, b and c , which are the coefficients of a quadratic equation and returns the value of the delta

Exercise 5: Create a method delta() that takes three integer values, a, b and c , which are the coefficients of a quadratic equation and returns the value of the delta, which is given by:   b ² - 4ac. Then call the method in the main and print the results.

Note: a = 8,  b = 2,   c = 3

Exercise 6: Use the method abs() to convert the value returned by the method delta() to a positive number
