1. The problem is to simplify or understand the expression $8c^2 - 2b^@$. 2. Notice that the expression contains an invalid character '@' which is not a standard mathematical symbol. 3. Assuming the '@' is a typo or error, we focus on the valid part: $8c^2 - 2b$. 4. The expression $8c^2 - 2b$ is already simplified as it contains unlike terms (one with $c^2$ and one with $b$). 5. If you want to factor the expression, you can factor out the common factor 2: $$8c^2 - 2b = 2(4c^2 - b)$$ 6. This is the factored form, which is simpler to work with in some contexts. 7. If '@' was intended to represent an exponent or another variable, please clarify for further assistance.
