Respuesta :

x^2- 10x +25

= (x - 5)^2

= (x - 5)(x - 5)

Answer

B. (x - 5)(x - 5)

Answer:  The correct option is

(B) [tex](x-5)(x-5).[/tex]

Step-by-step explanation:  We are given to factor the following expression :

[tex]E=x^2-10x+25~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We will be using the following factorization formula :

[tex](a-b)^2=a^2-2ab+b^2.[/tex]

From (i), we have

[tex]E\\\\=x^2-10x+25\\\\=x^2-2\times x\times 5+5^2\\\\=(x-5)^2\\\\=(x-5)(x-5).[/tex]

Thus, the required factored form of the given expression is [tex](x-5)(x-5).[/tex]

Option (B) is CORRECT.
