<prompt> Acha Px iwe polynomial kama hiyoPx P0 P1 x P2 x2na P-1 1. Tafuta Px.  <response>: Kuweka x -1, x 1, na x 2, tunapataanzaalign1 P-1 P0 - P1 P2, P1 P0 P1 P2, P2 P0 2P1 4P2,mwishoalignmtawalia. Kutatua hili kama mfumo wa milinganyo katika P0, P1, na P2, tunapata P0 -1, P1 -1 , na P2 1, hivyoPx x2 - x - 1.
