We are given the following expression
[tex]-24n^2+96n[/tex]Let us factor out the expression.
Notice that you can take -24n common so the expression becomes
[tex]-24n^2+96n=-24n\mleft(n-4\mright)[/tex]Therefore, the given expression can be written as the product of -24n and (n - 4)
[tex]-24n(n-4)[/tex]
