If α and ...
Question
If
α
and
β
are the two zeroes of a polynomial
x

and
−
β

Solution
If
α
,
β
are zeros of
x
2
+
6
x
+
a
=
0
-------- (1)
then they satisfy the equation as
x
2
−
(
α
+
β
)
x
+
α
β
=
0
where
α
+
β
=
6
&
α
β
=
a
now
α
→
−
α
←
β
→
−
β
then
x
2
+
(
α
+
β
)
x
+
α
β
=
0
Putting values we get
x
2
−
6
x
+
a
=
0
-------- (2)
equation is polynomial whose zeros aee
−
α
,
−
β
