#### Answer

$6m^3-7m^2-30m+25$

#### Work Step by Step

Using the Distributive Property, the product of the given expression, $
(2m-5)(3m^2+4m-5)
$ is
\begin{array}{l}\require{cancel}
2m(3m^2)+2m(4m)+2m(-5)-5(3m^2)-5(4m)-5(-5)
\\\\=
6m^3+8m^2-10m-15m^2-20m+25
\\\\=
6m^3+(8m^2-15m^2)+(-10m-20m)+25
\\\\=
6m^3-7m^2-30m+25
.\end{array}
