The order and degree of the differential equation d y d x -4 d y d x -7 x=0 are respectively.

Options

  1. A2 and 2
  2. B1 and 2
  3. C1 and 1
  4. D2 and 1

Correct answer

B. 1 and 2

Step-by-step solution

aligned & d y d x -4 d y d x -7 x=0 & d y d x =4 d y d x +7 x and squaring both sides, we get & d y d x =16 ( d y d x )^2+56 x ( d y d x )+49 x^2 & Order =1, degree =2 aligned
