Question 230144: Can someone please help me with this?
Factor out -1 from the polynomial.
4-5b
Thank you,
Jerry
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
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)
