Factor x(x-3) - 25(x-3)

To whom it may concern: I got it, even though my shitty textbook is encrypted with AES-256. Could someone verify the terminology I used in my answer below?

 

x(x-3) - 25(x-3) share the same coefficient, namely (x-3), so:

 

x(x-3) - 25(x-3) = (x-25)(x-3)

I think I would say that   x  (x-3)       and    -25  (x-3)    share a common FACTOR  '(x-3)'

 

so     (x    -     25)    (x-3)     using distributive property in reverse...
