Dear
Student
,
(
5
x

×
(
3
2
x
-
8
)
=
225

Now
,
We
should
find
factor
of
225
;
225
=
3
×
3
×
5
×
5
⇒
225
=
3

So
,
We
can
write
225
in
the
factor
of
3
and
5
;
(
5
x
-
3
)
×
(
3
2
x
-
8
)
=
225
⇒
(
5
x
-
3
)
×
(
3
2
x
-
8
)
=
3
2
×
5
2
Comparing
power
of
5
,
we
get
;
x
-
3
=
2
⇒
x
=
5
Comparing
power
of
3
,
we
get
;
2
x
-
8
=
2
⇒
2
x
=
10
⇒
x
=
5
