We consider the non-homogeneous initial value problem zy" – 4ry' + 6y = -12z-1, y(1) = -5, y'(1) = -9 By looking for solutions in the form y = z' in the homogeneous Euler-Cauchy problem Az?y" + Bry' + Cy = 0, we obtain a auxiliary equation Ar? + (B - A)r +C = 0 which is the analog of the auxiliary equation in the const: coefficient case. (1) For this problem find the auxiliary equation: (2) Find the roots of the auxiliary equation: (enter your results as a comma separated list ) (3) Find a fundamental set of solutions y1, 2 (enter your results as a comma separated list). Then the complementary solution is y. = C1yı + c2y2- (4) For the non-homogeneous problem we need to apply the variation of parameters formula to find a particular solution yp. Carrying this out you obtain Yp = Recall that the general solution is y = Ye + Yp. Find the unique solution satisfying y(1) = -5, y'(1) --9
