Solution
Given, polynomial
3
x
5
+
11
x
4
+
90
x
2
−
19
x
+
53
divided by
(
x
+
5
)
.
Then,
f
(
x
)
=
3
x
5
+
11
x
4
+
90
x
2
−
19
x
+
53
.
The polynomial is divided by
(
x
+
5
)
.
Then put
(
x
+
5
)
=
0
⟹
x
=
−
5
, we get,
f
(
−
5
)
=
3
(
−
5
)
5

)
4

(
−

=
−
9375
+
6875
+
2250
+
95
+
53
=
−
102
.
So, when
f
(
x
)
=
x
3
+
1
is divided by
x
+
1
, the remainder obtained is
−
102
.
