The general solution of the differential equation d y d x + (x+y)= (x-y) is

Options

  1. Ay+ x= C
  2. By 2 +2 x= C
  3. Cy 2 + x= C
  4. DNone of these

Correct answer

B. y 2 +2 x= C

Step-by-step solution

The equation is, d y d x = (x-y)- (x+y)=2 x (-y) d y y +2 x d x=0 e c y d y+2 x d x= C y 2 +2 x= C
