The remainder is
=
18
Explanation:
Apply the remainder theorem :
When the polynomial
f
(
x
)
is divided by
(
x
−
c
)
, then
f
(
x
)
=
(
x
−
c
)
q
(
x
)
+
r
(
x
)
And when
x
=
c
f
(
c
)
=
0
⋅
q
(
x
)
+
r
=
r
where
r
is the remainder
Here,
f
(
x
)
=
x
3
−
2
x
2
+
5
x
−
6
and
c
=
3
Therefore,
f
(
3
)
=
27
−
18
+
15
−
6
=
18
The remainder is
=
18
