ANSWER: c²+16c+64
STEP BY STEP EXPLANATION:
(8+c)²
= (8+c)×(8+c)
•use the FOIL METHOD
= 8×8+8c+8c+c×c
=64+16c+c²
•use the commutative property
SO the answer is : c²+16c+64
hope it helps

Now we move to outside . multiply the outside terms of each expression.
Next up are the inside terms. Multiply these from each expression.
Finally, we have the last terms. Multiply the last terms from each expression.
