Answer:
(b-1)(b-1)
Step-by-step explanation:
If you don't see a perfect square here, then your objective since the coefficient of b^2 is 1 and this is a quadratic, is to find two numbers that multiply to be 1 and add up to be -2.
-1(-1)=1 and -1+(-1)=-2.
So the factored form is (b-1)(b-1) or (b-1)^2.
