Given:
Given that the expression is
We need to simplify the value and determine the undefined value.
Simplification:
Let us simplify the given expression.
Factor out the term
from the expression, we get;
Factor out the term
from the denominator of the expression, we get;
Cancelling the common terms, we have;
Thus, the simplified expression is
Undefined value:
The undefined value of the expression
is
Thus, the solution is
,
