x(y + 1) - m(y + 1)

a(m + n) + b(m + n) + c(m + n)

4ab - 3ay - 5ab + 7ay

9ab + 6b + 12ac + 8c

Answer 1

a)

= x(y + 1) - m(y + 1)

= (y + 1).(x - m)

********************************************
b)

= a(m + n) + b(m + n) + c(m + n)

= (m + n).(a + b + c)

******************************************
c)

= 4ab - 3ay - 5ab + 7ay

= 4ab - 5ab - 3ay + 7ay

= - ab + 4ay

= a( - b + 4y)

*****************************************
d)

= 9ab + 6b + 12ac + 8c

= 3b.(3a + 2) + 4c.(3a + 2)

= (3a + 2).(3b + 4c)
