To simplify the expression [tex]\( -(2a - 1) \)[/tex], follow these steps:
1. Distribute the negative sign through the expression inside the parentheses.
2. Apply the distribution to both terms within the parentheses:
[tex]\[
-(2a - 1) = -1 \cdot 2a + (-1) \cdot (-1)
\][/tex]
3. Calculate the products:
[tex]\[
-1 \cdot 2a = -2a \quad \text{and} \quad (-1) \cdot (-1) = 1
\][/tex]
4. Combine the resulting terms:
[tex]\[
-2a + 1
\][/tex]
So, the simplified form of the expression [tex]\( -(2a - 1) \)[/tex] is:
[tex]\[
1 - 2a
\][/tex]
