Step-by-step explanation:
Factor the equation, note that both 2 and 5 are prime numbers, therefore they can only have themselves and 1 as a factor. Therefore a factorisation of:
2
x
2
−
3
x
−
5
=
(
2
x
−
a
)
(
x
−
b
)
=
0
Is likely.
With either
(
|
a
|
,
|
b
|
)
=
(
1
,
5
)
,
(
5
,
1
)
By inspection we see
a
=
5
,
b
=
−
1
, therefore we have:
2
x
2
−
3
x
−
5
=
(
2
x
−
5
)
(
x
+
1
)
=
0
⇒
x
=
−
1
,
5
2
