If A= [ array ccc 0 & x & 16 x & 5 & 7 0 & 9 & x array ] is singular, then the possible values of x are

Options

  1. A0,1,-1
  2. B0,+12-12
  3. C0,5,-5
  4. D0,4,-4

Correct answer

B. 0,+12-12

Step-by-step solution

Since, A is singular matrix, then aligned | array ccc 0 & x & 16 x & 5 & 7 0 & 9 & x array |=0 -x [x² .&-144]=0 x=0, 12 aligned
