Question 231210
I assume the problem is:
Express f(x) in the form {{{f(x)=q(x)(x-k)+r}}} for {{{f(x) = -3x^3 + 5x -6}}} for {{{k= -1}}}<br>
The easy way to do this is with synthetic division:
<pre>
-1 |   -3   0   5   -6
----        3  -3   -2              
      ----------------
       -3   3   2   -8
</pre>
So
{{{f(x) = (-3x^2 +3x + 2)(x - (-1)) + -8}}}
