The answer to your question is the letter C. (x + 5/2)² = 9/4

Step-by-step explanation:

Data

                x² + 5x + 8 = 4

- Subtract 8 in both sides

                x² + 5x + 8 - 8 = 4 - 8

- Simplify

                x² + 5x +         = -4

- Divide 5 by 2

                5/2

- Write (5/2)² in both sides

                x²+ 5x + (5/2)² = -4 + (5/2)²

- Simplify

                x² + 5x + 25/4 = -4 + 25/4

                (x + 5/2)² = -16/4 + 25/4

- Result

                (x + 5/2)² = 9/4
