Simplifying the Expression: (8b^3 + 8)  (6  7b^3)
This expression involves combining like terms and simplifying the parentheses. Here's a stepbystep breakdown:

Distribute the negative sign: The minus sign in front of the second set of parentheses means we multiply each term inside by 1:
(8b^3 + 8) + (1 * 6) + (1 * 7b^3)

Simplify the multiplication:
(8b^3 + 8)  6 + 7b^3

Combine like terms: Identify the terms with the same variable and exponent (or no variable at all) and combine their coefficients:
(8b^3 + 7b^3) + (8  6)

Final simplification:
15b^3 + 2
Therefore, the simplified form of the expression (8b^3 + 8)  (6  7b^3) is 15b^3 + 2.
