Choose the equation that shows a step in the process of completing the square on the given quadratic.y = x2 + 8x – 3

To complete the square for x² + 8x, take half of 8 and square it: (8 ÷ 2)² = 16. Add 16 and subtract 16 so the expression’s value stays the same: y = x² + 8x + 16 − 3 − 16. This is choice C.
