The correct Answer is:
To find the zero of the polynomial \( p(x) = 2x + 5 \), we need to determine the value of \( x \) for which \( p(x) = 0 \). ### Step-by-Step Solution: 1. **Set the polynomial equal to zero**: \[ 2x + 5 = 0 \] 2. **Isolate the term with \( x \)**: To do this, subtract 5 from both sides: \[ 2x = -5 \] 3. **Solve for \( x \)**: Now, divide both sides by 2: \[ x = \frac{-5}{2} \] Thus, the zero of the polynomial \( p(x) = 2x + 5 \) is: \[ \boxed{-\frac{5}{2}} \]
