Write a method called quadratic that solves quadratic equations and prints their roots. Recall that a quadratic equation is a polynomial equation in terms of a variable x of the form ax2 + bx + c = 0. The formula for solving a quadratic equation is ???????2?4????/2??Your method should accept the coefficients a, b, and c as parameters and should print the roots of the equation. You may assume that the equation has two real roots, though mathematically this is not always the case. Write a complete program in which the main program calls the method three times for quadratic(1, -7, 12); quadratic(3, 9, 6) and quadratic(1, 0, -5). NOTE: You will need to use the math class to take the square root.
