Answer:

(b + 7)(a + 4)

Step-by-step explanation:

ab + 7a + 4b + 28

separate the polynomial into 2 sections

(ab + 7a) (+ 4b + 28)

simplify each expression

a(b + 7)

4(b + 7)

you see that you have (b + 7) in both expressions. take that aside.

(b + 7)

you are left with a and positive 4. put these two together

(a + 4)

now put the expressions together

(b + 7)(a + 4)

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{(b + 7)(a + 4)}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ab + 7a + 4b + 28}[/tex]

Take a common

[tex] \dashrightarrow{ \sf{a(b + 7) + 4b + 28}}[/tex]

Take 4 common

[tex] \dashrightarrow{ \sf{a(b + 7) + 4(b + 7)}}[/tex]

Take ( b + 7 ) common

[tex] \dashrightarrow{ \sf{(b + 7)(a + 4)}}[/tex]

Hope I helped!

Best regards! :D
