Question
How to find zeroes of quadratic polynomial?? also give an example
Open in App
Solution
Let
p
x
be
a
polynomial
.
If
p
α
=
0
,
then
we
say
that
α
is
the
zero
of
the
polynomial
.
Finding
the
zeroes
of
of
a
polynomial
p
x
means
solving
the
equation
p
x
=
0
Consider
a
polynomial
x
2
-
5
x
+
6
.
Let
p
x
=
x
2
-
5
x
+
6
Now
,
zeroes
of
p
x
are
given
by
solving
the
equation
p
x
=
0
Now
,
p
x
=
0
⇒
x
2
-
5
x
+
6
=
0
⇒
x
2
-
3
x
-
2
x
+
6
=
0
⇒
x
x
-
3
-
2
x
-
3
=
0
⇒
x
-
2
x
-
3
=
0
⇒
x
-
2
=
0
and
x
-
3
=
0
⇒
x
=
2
and
x
=
3
So
,
2
and
3
are
the
zeroes
of
p
x
.
