Which polynomial does the model represent?

A black square, two white rods, one black rod, one white unit block and three black unit blocks are shown. (1 point)
–x³ + 2x² – 3x + 2
x² + x – 2
–x² – x + 2
–x² + x – 2

Lets say black is negativa and white is positive. A black square would mean -x^2, one white rod can get canceled out by a black on so +x is left, and two black unit blocks are left. Therefore its -x^2+x-2.
