Answer:

`\left(x+8\right)\left(x-8\right)`

Explanation:

⇒ Given info:

Factor completely
`x^2 -64`

⇒ Solution:

Rewrite 64 as 8 ² because 8² is equal to 64. 8 ² = 8 × 8 = 64.

`=x^2-8^2`

Applying difference of two squares formula:
`x^2-y^2=\left(x+y\right)\left(x-y\right)`

`=x^2-8^2=\left(x+8\right)\left(x-8\right)\\`

`=\left(x+8\right)\left(x-8\right)`

Answer~:
`\left(x+8\right)\left(x-8\right)`
