Step-by-step explanation:
Dividing x
3
+3x
2
+3x+1 by 5+2x
So, x
3
+3x
2
+3x+1 is dividend and 5+2x is divisor.
Put, 5+2x=0
∴ x=
2
−5
Let p(x)=x
3
+3x
2
+3x+1
Putting x=
2
−5
p(
2
−5
)=(
2
−5
)
3
+3(
2
−5
)
2
+3(

)+1
=

=
8
−125+150−60+8
=
8
−27
Thus, reminder of p(
2
−5
)=
8
−27
.
∴ We will get reminder as
8
−27
when x
3
+3x
2
+3x+1 is divided by 5+2x.
