$- 2 p + 1$ $-2p + 1$

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

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

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

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

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