Question:
Factor [tex]64-x^2[/tex]
(8 - x)(8 - x)
(8 + x) (8 - x)
(X + 8)(x-8)
Answer:
Option B: [tex](8+x)(8-x)[/tex] is the factor
Explanation:
Given that the expression is [tex]64-x^2[/tex]
We need to find the factor of the given expression.
Let us rewrite the expression as [tex]8^2-x^{2}[/tex]
Since the expression is of the form [tex]a^2-b^2[/tex], let us use the identity [tex]a^2-b^2=(a+b)(a-b)[/tex]
where a = 8 and b = x
Substituting the values in the identity, then the expression can be written as
[tex]8^2-x^{2}=(8+x)(8-x)[/tex]
Thus, the factor of the expression is [tex](8+x)(8-x)[/tex]
Hence, Option B is the correct answer.
