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.
