Answer:
Option d. 0
Explanation:
The given polynomial is x + ?x-36.
We are asked in this question to find the number that should replace the question mark to produce a difference of square.
The answer will be option d. i.e. 0. (Answer)
Since, if we put 0 in place of the question mark, then the polynomial becomes
x +0 -36 =x-36
And it can be expressed as (√x)²- 6² i.e. difference of two squares.
