Given:

The expression is

[tex]13ab+15ab[/tex]

To find:

The equivalent expressions in factored form.

Solution:

We have,

[tex]13ab+15ab[/tex]

In the given terms 13ab and 15ab, then common factors are only a and b because 13 is a prime number. So, the greatest common factor is ab.

Distributive property of multiplication over addition:

[tex]a(b+c)=ab+ac[/tex]

By using greatest common factor and the distributive property, we get

[tex]13ab+15ab=ab(13+15)[/tex]

[tex]13ab+15ab=ab(28)[/tex]

[tex]13ab+15ab=28ab[/tex]

Therefore, the required equivalent expression is [tex]28ab[/tex].
