Since when a polynomial P(x) is divided by x-2, the remainder is 3 , we letP(x) = Q(x) * (x - 2)(x - 3) + k(x - 2) + 3When it is divided by x-3, the remainder is 2 , by remainder theorem ,P(3) = 20 + k(3 - 2) + 3 = 2k = - 1SoP(x) = Q(x) * (x - 2)(x - 3) - (x - 2) + 3when P(x) is divided by (x-2)(x-3). , the remainder is - (x - 2) + 3= - x + 5
