subtract+polynomials

1. What are the steps for subrtacting polynomials? separate into like terms, plug and chug

2. how are adding and subtracting polynomials the same? they are the same because you use the same formula

3. how are they different? they are different because although you use the same formula, you have to look and see whether you are adding or subtracting.

additive inverse is a fancy way of saying just look and see if it's possitive or negative, and write that for your -/+ symbol, so dont be confused.
