Answer:
Distribute

:
We need to distribute the
−

-9
−
9
across the terms inside the parentheses.
\newline

c
=

c
-9 \times -2c = 18c

-9 \times -9 = 81

Combine distributed terms:
Now, we combine the distributed terms with the original term outside the parentheses.
6
c
+
18
c

81
6c + 18c + 81
6

Combine like terms:
Next, we combine like terms, which are the terms with the variable
c
c
c
.
6
c

18
c
=
24
c
6c + 18c = 24c

c
=

c
Write simplified expression:
Finally, we write down the simplified expression, which includes the combined like terms and the constant term.
