Answer: -7b² + 2b - 8
Step-by-step explanation:
Given expression
3 - b (7b + 2) + 3b - (11 - b)
Expand parentheses and apply the distributive property if necessary
=3 - b · 7b - b · 2 + 3b - 11 + b
=3 - 7b² - 2b + 3b - 11 + b
Combine like terms
=-7b² + (3b - 2b + b) + (3 - 11)
=[tex]\boxed{-7b^2+2b-8}[/tex]
