Hi.

So I'm new to differential equations (it has been a month since I started attending this course).

A linear equation, quite obviously... However I'm pretty much not able to proceed due to complicated integration.

And I expected something reasonably elegant...

I tried to solve for y' , which seems to be

But once more I am not able to proceed...

Code:

`\[3{x^2} - y = y'\sqrt {{x^2} + 1} \]`

Code:

`\[5y + {(y')^2} = x(x + y')\]`

I tried to solve for y' , which seems to be

Code:

`\[y' = \frac{{x \pm \sqrt {5{x^2} - 20y} }}{2}\]`

But once more I am not able to proceed...
