i factored
15A^2B  10AB^2
into...
(15A  10B)(15A + 10B)
am i doing it correctly? because im pretty confused.
thanks :]
No, you are confused. This is not a difference of squares. Neither the first term or the last is a perfect square.
Here, there are common factors. What is a common factor of 15 and 10. Say 5.
What is a common factor of A^2, and A?
of B and B^2?
So pull out the common factor..
5AB and multiply it with the remainder..
5AB(3A  2B).
check that by multipling it out.
