Answer:
20000000
Step-by-step explanation:
The equation modeled is 
The given equation Much easier to understand with the symbol 
x x .x -1
x x² x² x² -x
-1 -x -x- x +1
That is how I interpreted the "tile" set up.
Now count up the factors:
There are 3 x² . There are 4 -x and a +1
That's the third answer choice.
