Differential Equation

[quartz hull]

Someone tell me why with this integrating factor I can't convert this linear equation into an exact one?

Hello. I think it's e^(integral of R(x))

[quartz hull]

If that's it

What's the problem with that?

[umbral coyote]

The integrating factor is e^(integral R(x)), not e^(R(x))

That's why it doesn't work

[merry lodge]

so

actually you need to integrate that R(x)

[merry lodge]

true

ah, true I overlooked it, thanks xd

How I solve the part is below (I know there is a formula to solve it directly, but I want to do it step by step)
