Answer:

-16c² + 1

Step-by-step explanation:

Use FOIL.

First: -4c × 4c = -16c²

Outside: -4c × 1 = -4c

Inside: 1 × 4c = 4c

Last: 1 × 1 = 1

      -16c² - 4c + 4c + 1

Simplify.

      -16c² + 1

Make sure you're starting with the highest degree term and going down; that's what standard form means. In this case -16c² has the highest exponent so it goes first, and then 1 doesn't have any variables, so it comes next.
