Match the solution of the differential equation in the text to the following differential equation:
Differential equation in text = y' + P(x)y = Q(x) (standard form)
NOTE: 1) write the equation in standard form
2) find the integrating factor: u(x) = e^(ʃP(x)dx)
3) evaluate the integral to find the general solution: y = 1/(u(x)) ʃ Q(x)u(x)dx
y' - 2xy = x
This provides an example of finding a general solution to a differential equation using an integrating factor.
