Answer:

(2b+5)(5a+6)

Explanation:

Rearrange the expression to make it easy to factor...

10ab + 12b + 30 + 25a

We can factor the first half of the expression and the second half separately...

10ab+12b

The greatest common factor is 2b, so we can divide both terms by 2b to get...

2b(5a+6)

30+25a

The greatest common factor is 5, so we can divide both terms by 5 to get...

5(6+5a)

2b(5a+6)+5(5a+6)

Since both 2b and 5 are being multiplied by 5a+6, we can combine them to get...

(2b+5)(5a+6)
