The expression you provided is:

$-2 + 6p + 8$

To simplify this expression, combine the constant terms $-2$ and $8$:

$-2 + 8 + 6p = 6p + 6$

So, the simplified form of the expression is:

$6p + 6$

Would you like more details on any part of this process?

Here are five related questions to expand your understanding:

1. How would you factor the expression $6p + 6$?
2. What happens if you set $6p + 6 = 0$? What would the value of $p$ be?
3. Can you write the expression $6p + 6$ as a product of a constant and a binomial?
4. How would the expression change if you subtract $4p$ from $6p + 6$?
5. What is the result if you evaluate the expression $6p + 6$ for a specific value of $p$, say $p = 2$?

Tip: When simplifying algebraic expressions, always combine like terms first to make the expression more manageable.
