If y=2 x+3 x and y+A d^2 y d x^2 =B , then the values of A , B are respectively

Options

  1. A0,1
  2. B0,-1
  3. C-1,0
  4. D1,0

Correct answer

D. 1,0

Step-by-step solution

aligned & y=2 x+3 x & d y d x =2 x-3 x & d^2 y d x^2 =-2 x-3 x=-(2 x+3 x)=-y & y+ d^2 y d x^2 =0 aligned We have y+A d^2 y d x^2 =B A=1, B=0
