If (x-2) is a common factor of the expressions x^2+a x+b and x^2+c x+d , then b-d c-a is equal to

Options

  1. A-2
  2. B-1
  3. C1
  4. D2

Correct answer

D. 2

Step-by-step solution

Since, (x-2) is a common factor of the expressions x^2+a x+b and x^2+c x+d array rlrl & 2 a+b =2 c+d & b-d =2(c-a) & b-d c-a =2 array
