Using synthetic division to find the remainder we get:
Again, our answer this time is not a quotient, but the remainder.
Final answer: f(-1) = -9
Using synthetic division to find the quotient we get:
Note how the remainder is 0. This means that (x - 1/2) is a factor of .
We need to finish this problem by setting this equal to zero and
solving it:
*Factor the difference
of squares
*Set 1st factor = 0
*Set 2nd factor = 0
*Set 3rd factor = 0
