To simplify the expression (6b³ + 6 − b⁴) − (−8b³ − 6b⁴ + 2), we can perform the subtraction inside the parentheses by distributing the negative sign:

(6b³ + 6 − b⁴) − (−8b³ − 6b⁴ + 2) = 6b³ + 6 − b⁴ + 8b³ + 6b⁴ - 2

Next, we can combine like terms by adding or subtracting coefficients of the same variable:

= (6b³ + 8b³) + (6 - 2) + (-b⁴ + 6
