Question

How do you combine the like terms to make a simpler expression: `-4p+(-2)+2p+3`?

Answer 1

`-2p + 1`

Explanation:

`-4p + (-2) + 2p + 3`

Adding a negative number is the same thing as the negative number itself, so:
`-4p - 2 + 2p + 3`

Now you combine like terms:
`-4p + 2p = -2p`
`-2 + 3 = 1`

And when you put them together you get:
`-2p + 1`
