Square both sides:
Collect like terms and put into standard form:
Note that
and
, so:
Check for extraneous roots:
False, therefore
is extraneous.
True, therefore
is valid.
===================================================================
Raise each side to the third power:
Expand the binomial:
Collect like terms, leave in standard form:
Note that
,
, and
so:
Check for extraneous roots:
, True:
is a valid root.
, True:
is a valid root.
