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.
