Question

introduction to x - (x + 2)

Explanation:

Step1: Remove parentheses

To simplify \( x - (x + 2) \), we first distribute the negative sign to the terms inside the parentheses. The rule for distributing a negative sign is \( a - (b + c)=a - b - c \). So, \( x-(x + 2)=x - x-2 \).

Step2: Combine like terms

The terms \( x \) and \( -x \) are like terms. When we combine \( x - x \), we get \( 0 \). So, \( x - x-2=0 - 2=-2 \).

Answer:

\(-2\)
