To perform: The addition or subtraction in the rational expression

Answer to Problem 42E
The simplified form of the rational expression
Explanation of Solution
Given information: The rational expression is
Calculation:
Here, the denominators in the expression
So make them the same denominator by cross multiplication.
From the calculation, it is observed the denominators in the expression
Perform the subtraction operation in the expression
Thus, the simplified form of the rational expression
