I have to factor this trinomial b^2 - 6b -7, I think the answer is (b -1) ( b + 7)

b^2 - 6b -7 factors into (b +1) ( b - 7)
You were close.

the correct answer is ( b - 7 ) ( b + 1 )
because -7 + 1 = -6 = the middle term

it can be done this way:
b^2 - 6b -7
= b^2 - 7b + b -7
= b(b-7)+1(b-7)
= (b+1)(b-7)
thats it.

that's a binomial, not a trinomial.
answer is (b - 7)(b+1)
