Question

A binomial has been partially factored, as shown below:

x2 − 25 = (x + 5)(_____)

Which of the following binomials represents the missing factor?

(x − 5)
(x + 5)
(x − 20)
(x + 20)

Answer 1

$x^2-25=(x+5)(x-5)$
Answer: (x-5).

Answer 2

Answer:

option (A) is correct that is $(x-5)$.

Step-by-step explanation:

The given binomial expression is given as:

$x^2-25$

We have to partially factorize it, therefore

$x^2-25=(x+5)(x-5)$

Hence,  from all the options given, the missing factor of the given expression is $(x-5)$.

Thus, option (A) is correct that is $(x-5)$.
