help please​

Answer 1

The answer is

(

x

+

5

)

(

x

−

5

)

.

(

x

2

−

25

)

fits the pattern of the difference of squares in which

(

a

2

−

b

2

)

=

(

a

+

b

)

(

a

−

b

)

.

The factorization of

Answer 2

Answer:

$\huge \text{(x + 5)(x - 5)}$

Step-by-step explanation:

${x}^{2} - 25 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \implies {x}^{2} - {5}^{2} \: \: \: \: \: \: \: \: \: \: \: \: \\ \implies (x + 5)(x - 5)$
