    rational zeros

    state all possible rational zeros for the following function:

    f(x)=4[x^3]-3[x^2]+x-12




    use synthetic divison to divide...

    T(x)=x^5-2[x^4]+3[x^2]-x-2 BY x+2

    State the quotient and the remainder...

    State the quotient and the remainder...
    You should get,
    x^4+3x+5+\frac{8}{x-2}
    Thus,
    \mbox{Quotient }=x^4-3x+5
    \mbox{Remainder }=8
    Q.E.D.
