Factor this trinomial. b^2-6b-7? your answer should consist of two binomials.

Short (b - 7)(b + 1)

The answer will consist of 2 factors each of which is a binomial. Please don't take that comment personally. It is just on we are told to be accurate.

This factors by sight. You do not need the quadratic formula (but you could use it).

(b - 7)(b + 1) are the two factors that you need. When you remove the brackets, you get b^2 - 6b- 7 back.

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
