Answer 2

The differential equation ydx + xdy + 2zdz = 0 is integrable.

Explanation:

Given - Differential equation = $ydx + xdy + 2zdz = 0$

We can write it as,

 $= d(xy) + 2zdz = 0$

Now, we will integrate this differential equation,

$= \int\limits { d(xy) + 2zdz } \, =0$

$= \int\limits { d(xy) } +\int\limits { 2zdz } \, =0$

$=xy+2z^2=0$

Hence, the given differential equation is integrable. So, option (b) is correct.
