The vaue of -z^2+13z^2-5z^2+7z^3-15z is z(7z^2+7z-15).

Step-by-step explanation:

We have,

-z^2+13z^2-5z^2+7z^3-15z

To find, the vaue of -z^2+13z^2-5z^2+7z^3-15z=?

-z^2+13z^2-5z^2+7z^3-15z

=(-z^2+13z^2-5z^2)+7z^3-15z

=(7z^2)+7z^3-15z

=7z^2+7z^3-15z

=7z^3+7z^2-15z

Taking common as z, we get

=z(7z^2+7z-15)

Hence, the vaue of -z^2+13z^2-5z^2+7z^3-15z is z(7z^2+7z-15).
