Answer
Quotient = $-4x^{2}+10x-21$
Remainder = $43$
Work Step by Step
Dividing a polynomial P(x) with (x-c) using synthetic division:
Set up a table in three rows:
1. 1st row: place c, followed by coefficients of the powers of x (do not skip zeros)
2. third row, : copy the leading coefficient (call it A)
3. The entry of the middle row in the next column is obtained by multiplying A with c.
4. The next entry of the third row is obtained by adding the two entries in rows 1 and 2.
5. Repeat steps 3 and 4 until the table is filled.
Interpret the result:
the last entry of the last row gives the remainder, and
the preceding entries are coefficients of the quotient.

Dividing with ($x+2$) ... $c=-2$
\begin{array}{l|cccc|cc}
-2&&-4&2&-1&1&&\\
&&&8&-20&42&&\\\hline
&&-4&10&-21&43&&\\
\end{array}Quotient = $-4x^{2}+10x-21$
Remainder = $43$
