Math question--Polynomials

So dd has a weird punnet square-like representation of a polynomial expression.

She has to figure out which expression the box-thing represents.


Both have the same "answer" but are FOILed differently.


OMG--are you following me?


So how do you "unfoil" something?

Is it something like this?


       2x          3


3x|   6x^2    |  9x


-4 |   -8x      |  -12



so it's 2x +3   times 3x-4, and when you add what is in the boxes, it's 6x^2  +x -12


If it's not something like this I have no idea. But when I've seen this done, it does look like a punnet square.
