See a solution process below:
Explanation:
The right side of the equation is a special form of quadratic:
a
2
−
b
2
=
(
a
+
b
)
(
a
−
b
)
Let
a
2
=
121
x
2
then
a
=
√
121
x
2
=
11
x
Let
b
2
=
1
then
1
=
√
1
=
1
Substituting gives:
121
x
2
−
1
2
⇒
(
11
x
+
1
)
(
11
x
−
1
)
We can then write the equation factored as:
y
=
(
11
x
+
1
)
(
11
x
−
1
)
