Question

Factorise:
a) 4a + ab =
b) 2a + 6b =
c) 5xy + 15x =
d) 12p + 16 =

Answer 1

a)

`4a + ab = \boxed{\bf{a(4+b)}}`

b)

`2a + 6b = \boxed{\bf{2(a + 3b)}}`

c)

`5xy + 15x = \boxed{\bf{5x(y + 3)}}`

d)

`12p + 16 = \boxed{\bf{4(3p + 4)}}`

Answer 2

the only thing you should do it to write the equation as two equation multiplying together:
a) a(4+b)
b) 2(a+3b)
c) 5x(y+3)
d) 4(3p+4)
i hope this is helpful :))
have a nice day
