The general solution of the differential equation y '- 3 / xy = x to the power of 3 and e to the power of X To be specific,

The formula is as follows: if you want the derivative of Y + P (x) y = q (x)
This problem is to regard - 3 / X as P (x) and "the third power of X and the x power of E" on the right side of the equal sign as Q (x)
The formula is as follows:
Y = e to the power of (∫ P (x) DX) multiplied by [∫ P (x) Q (x) DX + C] C is an arbitrary constant
