Simplifying the Expression (2n)/(2n+2)
The expression (2n)/(2n+2) can be simplified by factoring out a common factor of 2 in the numerator and denominator. Here's how:
1. Factoring out 2:
- Numerator: 2n = 2 * n
- Denominator: 2n + 2 = 2 * (n + 1)
2. Simplifying the expression:
(2n)/(2n+2) = (2 * n) / (2 * (n + 1))
Since we have a 2 in both the numerator and denominator, we can cancel them out:
= n / (n + 1)
Therefore, the simplified expression is n/(n+1).
Important Note: This simplified expression is valid for all values of n except for n = -1. This is because when n = -1, the denominator becomes zero, which makes the expression undefined.
Example:
Let's say n = 3:
- Original expression: (2 * 3) / (2 * 3 + 2) = 6 / 8
- Simplified expression: 3 / (3 + 1) = 3 / 4
As you can see, both expressions evaluate to the same value.
