How do i factor a^3b-ab^3-a^2+b

Answer 1

it isn't factorable

you already posted this and i already answered this!

Answer 2

I screw up typing the equation. the first term is now a^3(b) i had previously typed just a^3

Answer 3

it's still not factorable

Answer 4

it would be factorable if the term ab^3 was ab^2

but since it isn't you cannot factor it

(this is one example of why it isn't factorable)
