5. Are the following pair of sets equal ? Give reasons. (i)
A
=
{
2
,
3
}
,
B
=
{
x
:
x
\mathrm{A}=\{2,3\}, \quad \mathrm{B}=\left\{x: x\right.
A
=
{
2
,
3
}
,
B
=
{
x
:
x
is solution of
x
2
+
5
x
+
6
=
0
}
\left.x^{2}+5 x+6=0\right\}
x
2
+
5
x
+
6
=
0
}
(ii)
A
=
{
x
:
x
\mathrm{A}=\{x: x
A
=

x
:
x
is a letter in the word FOLLOW
}
\}
}
B
=
{
