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 
TSO
a)
[tex]4a + ab = \boxed{\bf{a(4+b)}}[/tex]

b)
[tex]2a + 6b = \boxed{\bf{2(a + 3b)}}[/tex]

c)
[tex]5xy + 15x = \boxed{\bf{5x(y + 3)}}[/tex]

d)
[tex]12p + 16 = \boxed{\bf{4(3p + 4)}}[/tex]
