To find: The simplified form of given rational expression.
Answer to Problem 20E
The simplified form of the rational expression
Explanation of Solution
Given information:
The rational expression
Formula used:
To simplify rational expression factor out the numerator and denominator separately.
Calculation:
Consider the rational expression
Recall that to simplify rational expression factor out the numerator and denominator separately.
Strike off the common factors,
Observe that the original expression that is
So, the simplified expression is equivalent to original expression when
Thus, the simplified form of the rational expression
