Find the number that we can place in the box so that the resulting expression can be factored as the product of two linear factors.

\[3mn - 6m + 5n + \boxed{\phantom{00}}\]

Sorry! This is just really confusing to me right now :(

3mn - 6m + 5n + ?

Factoring "3mn - 6m"

3m(n - 2) + 5n + ?

We need to have it look like this:

3m(n - 2) + 5(n - 2)

So:  ?  =  -10

Checking:

3mn - 6m + 5n - 10

3m(n - 2) + 5(n - 2)

(3m + 5)(n - 2)
