Your polynomial is 4-5b.

If you multiply this polynomial by (-1) * (-1) it will remain the same because (-1)^2 = 1

your expression becomes:

(-1) * (-1) * (4-5b).

If you multiply (-1) * (4-5b) you get (-4+5b) which is the same as (5b-4)

your expression becomes:

(-1) * (5b-4)

You have just factored out (-1) from your polynomial expression of (4-5b)
