Factor fully

What did you try?

An example is : 3x^2 + 6xy , when factored gives 3x(x+2y)

You 'move' the common factors out and insert brackets.

15a2b2 + 25a4b - 40a3b6

does that translate into:



If so...

Pull out all of the a's you can, then the b's and then look for a common factor among the constant numbers and pull that out. If you can, factor what's left...
