<prompt> Kuna nambari kamili a,b, na c kama hizox - ax - 10 1 x bx c.Weka thamani zote zinazowezekana za a, zikitenganishwa na koma.  <response>: Kuweka x 10, tunapatab 10c 10 1.Ama b 10 c 10 1 au b 10 c 10 -1.Ikiwa b 10 c 10 1, basi b c -9, nax - ax - 10 1 x - 92.Kwa kuwa x - 92 - 1 x - 10x - 8, a 8.Ikiwa b 10 c 10 -1, basi b c 11, nax - ax - 10 1 x - 112.Tangu x - 112 - 1 x - 12x - 10, a 12.Kwa hivyo, thamani zinazowezekana za a ni 8,12.
