If y= x+ x+ . . , then d y d x is

Options

  1. Ax 2 y-1
  2. Bx 1-2 y
  3. Cx 2 y-1
  4. D0

Correct answer

C. x 2 y-1

Step-by-step solution

y= x+ x+ x+ array ll & y= x+y & y^2= x+y array On differentiating both sides w.r.t. x , we get aligned & 2 y d y d x = x+ d y d x d y d x (2 y-1)= x & d y d x x 2 y-1 aligned
