Solution
The correct option is
B
Reciprocal Equation
Given equation is
2
x
4
−
9
x
3
+
14
x
2
−
9
x
+
2
=
0
....
(
i
)
The maximum power of
x
in this equation is
4
, so this is
4
t
h
degree equation
So, it is neither linear nor quadratic equation.
In reciprocal equation
a
x
4
+
b
x
3
+
c
x
2
+
d
x
+
e
=
0
, the multiplication of the roots i.e (
e
a
) should be
1
In the given equation
(
i
)
,
e
a
=
2
2
So the multiplication of roots is equal to one
Therefore, equation
(
i
)
is a reciprocal equation.
Hence, option C is correct.
