Simplifying binomial over trinomial?

Question

Write in simplest form

9 - b^2 / b^2 - b - 6

Please show work

Answer 1

[9 - b²] / [b² - b - 6] =
[(3 + b)(3 - b)] / [(b - 3)(b + 2)] =
-[(3 + b)(b - 3)] / [(b - 3)(b + 2)] =
-(3+b) / (b+2)

Answer 2

The question should be written as:-
(9 - b²) / (b² - b - 6)
= (3 - b).(3 + b) / (b - 3).(b + 2)
= - (b - 3).(3 + b) / (b - 3).(b + 2)
= - (3 + b) / (b + 2)
