The correct Answer is:
To find the value of \( a \) such that \( 2x^2 + x - a = 5 \) when \( x = 0 \), we can follow these steps: ### Step-by-Step Solution: 1. **Substitute \( x = 0 \) into the expression**: \[ 2(0)^2 + (0) - a = 5 \] 2. **Simplify the left side**: \[ 2 \cdot 0 + 0 - a = 5 \] This simplifies to: \[ 0 - a = 5 \] 3. **Rearrange the equation to solve for \( a \)**: \[ -a = 5 \] 4. **Multiply both sides by -1**: \[ a = -5 \] ### Final Answer: Thus, the value of \( a \) is \( -5 \). ---
