I'm going to assume you meant
rather than
First make a note to exclude
if it happens to come up as a potential root of the equation because -1 is not in the domain of the right hand side of the equation because -1 would make the denominator equal zero.
Second, move everything to the left of the equal sign, thus:
is your common denominator, so:
Simplify the numerator

Remember that
if and only if
and
, meaning that we need to solve for:
Oddly enough, this mess actually factors.
, hence

or

Since neither of these roots = -1, both are valid potential roots of the
equation. However, since we introduced an
term by applying the
common denominator, we need to check both roots against the possiblity that
one of them is extraneous.




First root checks.




Second root checks.
