Simplify
(a - b)(a - 6ab - b)
It's already simplified. I can expand it, but that's not really simplifying it.
It can be written as
(a-b)^2 - 6ab(a-b)
or in other ways, none of which are any simpler than what you have.
(a - b)(a - 6ab - b)
It can be written as
(a-b)^2 - 6ab(a-b)
or in other ways, none of which are any simpler than what you have.
