Consider the quadratic equation
a
x
2
+
b
x
+
c
=
0
ax^2+bx+c=0
a
x
2
+
b
x
+
c
=
0
where
a
,
b
,
c
a,b,c
a
,
b
,
c
are integers with
a
≠
0
a\ne 0
a
=
0
. Which of the following option(s) are true?
A
If
b
2
−
4
a
c
>
0
b^2-4ac>0
b
2
−
4
a
c
>
0
and a perfect square then there exists a rational root of the quadratic equation.
B
If
b
2
−
4
a
c
>
0
b^2-4ac>0
b
2
−
4
a
c
>
0
and not a perfect square then there exists a rational root of the quadratic equation.
C
If
b
2
−
4
a
c
<
0
b^2-4ac<0
b
2
−
4
a
c
<
0
and a perfect square then there exists a rational root of the quadratic equation.
D
If
b

−
4
a
c
<
0
b^2-4ac<0
b
2
−
