Simplifying the Expression ((1/x)-(1/2))/(x-2)
This article will guide you through simplifying the expression ((1/x)-(1/2))/(x-2).
Step 1: Finding a Common Denominator for the Numerator
The first step is to find a common denominator for the fractions in the numerator. The least common multiple of x and 2 is 2x. We can rewrite the expression as follows:
((2/2x)-(x/2x))/(x-2)
Step 2: Combining the Fractions in the Numerator
Now, we can combine the fractions in the numerator:
((2-x)/2x)/(x-2)
Step 3: Simplifying the Complex Fraction
The expression is now a complex fraction. To simplify, we can invert the denominator and multiply:
(2-x)/2x * 1/(x-2)
Step 4: Factoring and Cancelling
Notice that the numerator and denominator share a common factor of (x-2). We can factor out a -1 from the numerator to make this clearer:
(-1(x-2))/2x * 1/(x-2)
Now, we can cancel the (x-2) terms:
(-1)/2x
Conclusion
Therefore, the simplified form of ((1/x)-(1/2))/(x-2) is (-1)/2x, where x ≠ 2. It's important to remember that the expression is undefined when x = 2, as this would result in division by zero.
