Question

In the polynomial below, what number should replace the question mark to produce a difference of squares? x + ?X-36

O a.36
O b.6
O c.12
O d.O

Answer 1

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.
