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

Options

  1. A1 and 1 2
  2. B2 and 1
  3. C1 and 1
  4. D1 and 2

Correct answer

D. 1 and 2

Step-by-step solution

d y d x -4 d y d x -7 x=0 or d y d x =4 d y d x +7 x Squaring both side, aligned d y d x & =16 ( d y d x )^2+49 x^2+56 x d y d x Order & =1 and degree =2 aligned highest order derivative is ( d d x ) and its exponent is 2 .
