1. The quotient obtained by synthetic division is
-2x^2 - 6x + 1, and the remainder is
3/(x-3). 2. When
-2x^3 + 19x - 3 is divided by
x-3, the result is
-2x^2 - 6x + 1 with a remainder of
3/(x-3).

1. Let's complete the synthetic division table:

(it has been attached)

2. Now, write the answer in the requested form:


\[ -2x^3 + 19x - 3 = (-2x^2 - 6x + 1)(x - 3) + (3)/(x-3) \]

So, the quotient is
\(-2x^2 - 6x + 1\) and the remainder is
\((3)/(x-3)\). Therefore, the answer is:
\[ (-2x^3 + 19x - 3)/(x - 3) = -2x^2 - 6x + 1 + (3)/(x-3) \]

In synthetic division, we divide polynomials efficiently using a root of the divisor. In this case,
-2x^3 + 19x - 3 is divided by
x-3. The synthetic division table facilitates the process, showing coefficients and remainders.

The quotient,
-2x^2 - 6x + 1, represents the result of the division, and the remainder,
3/(x-3), is the fraction left over. The expression
-2x^3 + 19x - 3 can be reconstructed by multiplying the quotient and divisor, adding the remainder to form the original polynomial.
