x
4
+
10
x
3
+
35
x
2
+
50
x
+
29
by
(
x
+
4
)
is

Solution
x
4
+
10
x
3
+
35
x
2
+
50
x
+
29
=
(
x
4
+
10
x

25
x
2
+
50
x
+
24
)
+
5
Given :
(
x
+
4
)
is one of the factor of
x
4
+
10
x
3
+
35
x
2
+
50
x
+
24
And by using Synthetic Division we get another factor as
(
x
3
+
6
x
3
+
11
x
+
6
)
and the remainder
5
∴
a
=
−
6
,
b
=
11
and the remainder is
5
.
