Question

simplify each expression.
(6b³ + 6 - b⁴) - (8b³ - 6b⁴ + 2)
5b⁴ - 2b³ + 4
5b⁴ - 2b³ + 7
4b⁴ - 2b³ + 7
b⁴ - 2b³ + 7

Explanation:

Step1: Distribute the negative sign

$(6b^3 + 6 - b^4) - 8b^3 + 6b^4 - 2$

Step2: Group like terms

$(-b^4 + 6b^4) + (6b^3 - 8b^3) + (6 - 2)$

Step3: Combine like terms

$5b^4 - 2b^3 + 4$

Answer:

$5b^4 - 2b^3 + 4$
