(b) ax + bx - ay - by
(a) ab + 4a-36- 12 (6) ax + bx - ay - by
(C) 15p9 + 15 +9q + 25p
[NCERT]
Sol.
(a) ab + 4a - 36 - 12 can be written in groups as
ab - 3b + 4a - 12 = bla - 3) + 4 (a - 3)
(Here, there is no common factor of the terms but
= (a + b)x - (a
= (a + b) (x-)
(c) 15p9 + 15 +9q + 25p
= (15p9 +99)
= 39(5p + 3) +
= (5p + 3) (39
