solve it using augmented matrix. Also it is homework
4. Now we'll look at a nonhomogeneous example. The general form for these is y' + p(x)y = f(x).
For this problem, we will find solutions of the equation
+2xy= xe
(a) Identify p(x) and f(x) in the equation above.
p(x) =
f(x) =
(b) The complementary equation is y' + p(x)y = 0. Write the complementary equation.
(c) Find a solution for the complementary equation. We'll call this solution y₁. (You only need one
particular solution, so you can let k = 0 here.)
Y1 =
(d) Check that y₁ satisfies the complementary equation, in other words, that y₁+ p(x)y₁ = 0.
