Answer:
(x-10)(x+10)
Step-by-step explanation:
Here, the given expression,
[tex]x^2-100[/tex]
[tex]=(x)^2-(10)^2[/tex]
By using the identity [tex]a^2-b^2=(a+b)(a-b)[/tex]
[tex]=(x+10)(x-10)[/tex]
[tex]=(x-10)(x+10)[/tex] ( By the commutative property )
Since, further factorization is not possible,
Hence, the factors of [tex]x^2-100[/tex] are,
[tex](x-10)(x+10)[/tex]
Second option is correct.
