Open in App
Solution
Dear student
Since
α
and
β
are
the
roots
of
the
equation
x
2
+
5
x
+
5
=
0
So
,
α
+
β
=
-
5
and
αβ
=
5
Let
S
and
P
be
the
sum
of
roots
and
product
of
the
roots
of
the
required
eqaution
.
So
,
S
=
α
+
1
+
(
β
+
1
)
=
α
+
β
+
2
=
-
5
+
2
=
-
3
and
P
=
(
α
+
1
)
(
β
+
1
)
=
αβ
+
α
+
β
+
1
=
5
-
5
+
1
=
1
So
,
required
equation
is
k
x
2
+
3
x
+
1
where
k
is
a
non
-
zero
constant
