Question
We consider the initial value problem \( x^2y'' - 7xy' + 16y = 0, \, y(1) = -2, \, y'(1) = -9 \). By looking for solutions in the form \( y = x^r \) in an Euler-Cauchy problem \( Ax^2y'' + Bxy' + Cy = 0 \), we obtain an auxiliary equation \( Ar^2 + (B - A)r + C = 0 \) which is the analog of the auxiliary equation in the constant coefficient case. 1. For this problem find the auxiliary equation: [Input box] = 0 2. Find the roots of the auxiliary equation: [Input box] (enter your results as a comma-separated list) 3. Find a fundamental set of solutions \( y_1, y_2 \): [Input box] (enter your results as a comma-separated list) 4. Recall that the complementary solution (i.e., the general solution) is \( y_c = c_1y_1 + c_2y_2 \). Find the unique solution satisfying \( y(1) = -2, \, y'(1) = -9 \) \[ y = \] [Input box]
