Simplifying Polynomial Expressions

Question 5 • Algebra III A

Simplify 3 – b(7b + 2) + 3b – (11 – b).-7b2 + 2b - 10-7b2 + 2b - 88b - 6 -5b - 8

Answer
A
-7b2 + 2b - 10
B
-7b2 + 2b - 8
C
8b - 6
D
-5b - 8

Explanation

Distribute the minus signs: −b(7b + 2) = −7b² − 2b, and −(11 − b) = −11 + b. Combine like terms: −7b² + (−2b + 3b + b) + (3 − 11) = −7b² + 2b − 8. This matches choice B, −7b² + 2b − 8.
