You can put this solution on YOUR website!
First re-write 36-13b%2Bb%5E2 as b%5E2-13b%2B36
Then find two factors of 36 that are negative(b/c your middle term is negative and your last term is positive) that added together give you -13.
-9 and -4
so...
36-13b%2Bb%5E2
b%5E2-13b%2B36
%28b-9%29%28b-4%29
