O A. X- 14
O B. X-7
O C. X-1
O D. x-2

Answer 1

Kon'nichiwa!

To Acquire=>the binomials below is a factor of

`x {}^(2) - 5x - 14`

Explanation:

By Middle splitting method

=>

`x {}^(2) - 5x - 14 \\ = x {}^(2) + 2x - 7x - 14 \\ = x(x + 2) - 7(x + 2) \\ = (x - 7)(x + 2)`

Hence, (x-7) Is the required answer
