    Answer:

    X-2=0

    X=2

    P(X)=x^3-3x^2+3x-2

    Putting the value of X=2

    =2^3-3×2^2+3×2-2

    =8-12+6-2

    =-14+14

    =0

    So x-2 is a factor

    Answer:

    -6

    Step-by-step explanation:

    p(x)=x^3-2x^2-5x+4. g(x)=(x-2)

    x-2=0

    x=2

    p(2)=(2^3)-2(2^2)-5(2)+4

    p(2)=8-8-10+4

    p(2)=-6

    Since remainder is not zero, (x-2) is not a factor of p(x)
