<prompt> Acha px iwe ujazo wa polynomial kiasi kwamba p2 0, p-1 0, p4 6, na p5 8. Tafuta p7.  <response>: Kwa kuwa p2 p-1 0, px ni ya fomupx shoka bx - 2x 1kwa baadhi ya visanduku a na b. Kuweka x 4 na x 5, tunapataanzaalign4a b25 p4 6, 5a b36 p5 8,mwishoalignhivyoanzaalign4a b frac35, 5a b frac49.endalignKutatua, tunapata a -frac745 na b frac119. Kwa hivyo,px kushoto -frac745 x frac119 kulia x - 2x 1 -frac7x - 55x - 2x 145.Kwa hiyo,p7 -frac49 - 555845 frac163.
