Step-by-step explanation:
x=
a+2b
−
a−2b
a+2b
+
a−2b
=
a+2b
−
a−2b
a+2b
+
a−2b
×
a+2b
+
a−2b
a+2b
+
a−2b
=
(a+2b)−(a−2b)
(
a+2b
+
a−2b
)
2
=
2b
a+
a
2
−4b
2
(Using identities and then simplifying)
⇒2bx=a+
a
2
−4b
2
⇒2bx−a=
a
2
−4b
2
Squaring both sides, we get,
(2bx−a)
2
=a
2
−4b
2
⇒4b
2
x
2
+a
2
−4abx=a
2
−4b
2
⇒4b
2
x
2
−4abx+4b
2
=0
⇒bx
2
−ax+b=0.
