$x^2-x+1$
$x^2+x+1$

3. Division of $3x^2-5x-2$ by $2x^3-x^2-x+1$ is not permissible because $\cdots\cdots$
the divisor contains more terms than the dividend
the divisor has a higher degree than the dividend
the divisor is not factorable
the dividend is not factorable
4. Is it possible for a polynomial to be divided by two different linear functions with the resulting remainders being equal?
Yes, sometimes
Yes, always the case
No, never possible
Not sure
5. The remainder theorem states that if a polynomial $f(x)$ is divided by $ax+b$, then the remainder is $\cdots\cdots$?
$f(a/b)$
$f(-b/a)$
$f(-a/b)$
$f(a+b)$
6. The synthetic method of dividing polynomials has one limitation, namely:
it doesn't work for linear divisors
it only works for linear divisors
it is difficult to implement in practice

10. Write $\frac{x^3-3x^2+6x-6}{x+2}$ in the form Polynomial = Divisor $~\times ~$ Quotient + Remainder
$x^3-3x^2+6x-6=(x+2)(x^2+5x+16)+38$
$x^3-3x^2+6x-6=(x+2)(x^2+5x+16)-38$
$x^3-3x^2+6x-6=(x+2)(x^2-5x+16)-38$
$x^3-3x^2+6x-6=(x+2)(x^2-5x-16)-38$
