Implement a class QuadraticEquation whose constructor receives the coefficients a, b, c of the quadratic equation *ax*^{2} + *bx* + *c* = 0. Supply methods getSolution1 and getSolution2 that get the solutions, using the quadratic formula. Write a test class QuadraticEquationTester that constructs a QuadraticEquation object, and prints the two solutions, together with the values that you expect.
