8c-2c^3-12-3c^2

To simplify the expression \( 8c - 2c^3 - 12 - 3c^2 \), we can combine like terms. Here are the steps:

1. Rearrange the terms in descending order of the powers of \( c \): \[ -2c^3 - 3c^2 + 8c - 12 \]

2. Identify the like terms:

   • The term with \( c^3 \) is \( -2c^3 \).
   • The term with \( c^2 \) is \( -3c^2 \).
   • The term with \( c \) is \( 8c \).
   • The constant term is \( -12 \).

3. Since there are no like terms to combine, we keep the expression as: \[ -2c^3 - 3c^2 + 8c - 12 \]

The simplified expression is: \[ -2c^3 - 3c^2 + 8c - 12 \]
