Question

Question 6 What is the factored form of the expression below? 7 - 16 O OD (x-8)(x - 8) (x - 4)(x + 4) (x - 4)(x - 4) (x-8)(x + 8) Oo

Answer 1

If :

`x^2-16`
`\begin{gathered} \sqrt[]{x^2}=x \\ \sqrt[]{16}=4 \end{gathered}`

Then:

`x^2-16\text{ =(x-4)(x+4)}`

Answer: ( x - 4 ) ( x + 4 )
