Jun 21, 2017

See below.

#### Explanation:

Basically just multiply the first term in the first set of brackets by each term in the next set and do the same with the second term and add them together like the picture shown.

So yours would become

$\left(4 m\right) \left(2 m\right) + \left(4 m\right) \left(5\right) + \left(- 3\right) \left(2 m\right) + \left(- 3\right) \left(5\right)$

$= 8 {m}^{2} + 20 m - 6 m - 15$

$= 8 {m}^{2} + 14 m - 15$
