Answer:
[tex](x+10)(x-10)[/tex]
Step-by-step explanation:
Given : [tex]x^{2} -100[/tex]
To Find : What are the factors of [tex]x^{2} -100[/tex]
Solution:
[tex]x^{2} -100[/tex]
Since 100 =[tex]10^{2}[/tex]
[tex]x^{2} -10^{2}[/tex]
using property : [tex]a^{2} -b^{2} =(a+b)(a-b)[/tex]
[tex](x+10)(x-10)[/tex]
Thus the factors of [tex]x^{2} -100[/tex] are (x+10) and (x-10)
