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.
