Answer
Quotient =$0.11x-0.21$
Remainder = $0.241$
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 ($x+2.1$) $\qquad$... $c=-2.1$
\begin{array}{l|cc|cc}
-2.1&0.1&0&-0.2&&&&\\
&&-0.21&0.441&&&&\\ \hline
&0.1&-0.21&0.241&&&&\\
\end{array}
Quotient =$0.11x-0.21$
Remainder = $0.241$
