We effectively rewrite the equation as

In order for the LHS to be defined, we need to restrict  , or
, or  . Now, the LHS will vanish when the numerator is 0, which happens for
. Now, the LHS will vanish when the numerator is 0, which happens for

This value is indeed smaller than 4, so the solution is  .
