If (x+y)= x y+3 , then d y ~d x =

Options

  1. A( y x )^2
  2. B- ( x y )^2
  3. C- ( y x )^2
  4. D( x y )^2

Correct answer

C. - ( y x )^2

Step-by-step solution

aligned & (x+y)= x y+3 & ( x+y x y )=3 & x+y x y =e^3 & 1 y + 1 x =e^3 & Diff -1 y^2 d y ~d x - 1 x^2 =0 & d y ~d x =- y^2 x^2 aligned
