Common factor is (a - b)
(a - b) [ r - s ] are the factors.

factor it by moving the (a - b) out since it is the same factor of r and s in the initial equation:
(a - b)r - (a - b)s =
(a - b)(r - s)
of if you need to multiply it out:
(a - b)r - (a - b)s =
ra - rb -(sa - sb) =
ra - rb - sa + sb

(a-b)r-(a-b)s
= (a-b)(r-s)
i think
