Answer:
Step-by-step explanation:
from this equation you can see that you can pull out a 5b from the equation. This would give you
5b(2a+3)
As you can see, you can't go any further. To check yourself and make sure the equation is factored correctly, you can distribute 5b back into 2a and 3. This will leave you with the original equation, 10ab+15b. Good luck!
