If the equation has four distinct solutions then the number of integral values of k is

Options

  1. A4
  2. B5
  3. C6
  4. Dnone of these

Correct answer

B. 5

Step-by-step solution

_ t (t^2-2 ) t^2 ( 2- 1 t - 1 t^2 + 1- 1 t + 1 t^2 )( 2 -1) =1 Now || x -1|-6|= k has four distinct solutions if k (0,6) Number of integral values of k is 5
