What’s the remainder for this synthetic division problem?

3   |   1    5     -8     6

.    |         3    24   48

- - - - - - - - - - - - - - - -

.    |    1    8    16    54

That is to say,

The remainder is 54.

Another way of doing it is to apply the polynomial remainder theorem, which says the remainder upon dividing a polynomial by is exactly . So recognizing that the listed coefficients refer to

we find

the answer is vanilla
