Answer:
4(r+4)(r-4)
Step-by-step explanation:
If you factor it out, then it will be 4(r+4)(r-4). You can double check by multiplying it.
For this case we must factor the following expression:
[tex]4r ^ 2-64[/tex]
We take common factor 4:
[tex]4 (r ^ 2-16)[/tex]
We factor the expression within the parenthesis:
[tex]4 [(r-4) (r + 4)][/tex]
Finally we have that the factored expression is:
[tex]4 [(r-4) (r + 4)][/tex]
Answer:
[tex]4 [(r-4) (r + 4)][/tex]
