Question Part Points Submissions Used Solve the differential

Question Part Points Submissions Used Solve the differential equation by variation of parameters, subject to the initial conditions y(0) = 1, y\'(0) = 0.

y\'\' + 2y\' - 8y = 4e^-2x - e^-x

Solution

y\'\' + 2y\' ? 8y = 4 e^(?3x) ? e^(?x)

complementary solution, yc
y\'\' + 2y\' ? 8y = 0
auxiliary equation ==> r
