Explanation:
The equation
3
x
2
+
5
x
−
2
is of the form
a
x
2
+
b
x
+
c
=
0
where:
a
=
3
,
b
=
5
,
c
=
−
2
The Discriminant is given by:
Δ
=
b
2
−
4
⋅
a
⋅
c
=
(
5
)
2
−
(
4
)
⋅
(
3
)
⋅
(
−
2
)
=
25
+
24
=
49
As
Δ
>
0
there are two solutions,
The solutions are found using the formula:
x
=
−
b
±
√
Δ

⋅
a
As
Δ
=

,
x
=
