If d y d x = y+x y x x , then ( y x )=
Options
- Ac x²
- Bc x
- Cc x³
- Dx
Correct answer
B. c x
Step-by-step solution
We have, d y d x = y+x y x x ...(i) Given, differential equation is in homogeneous form. put y=v x in Eq. (i), we get v+x d v d x =v+ v 1 v d v= d x x Taking integration on both sides, we get ( v)= x+ c v x = c ( y x )=x c
