C) (y - 1)(y - 5)
Step-by-step explanation:
Hi there!
First you separate your expression into groups.
Now we take the common multiple out of each.
Since we have two (y - 5)s, we can pull it out of the equation as its own common multiple.
After we do that, we are left with y - 1. (we got this from taking the common multiples out)
Now we are just left with (y - 5)(y - 1)
Hope this helped!
