Answer:

The vertex is at (-8, -56).

Step-by-step explanation:

x^2+16x+8

= (x + 8)^2 - 64 + 8

= (x + 8) - 56.

The vertex is at (-8, -56).

MathPhys

Step-by-step explanation:

x² + 16x + 8

Complete the square.  Take half of b, square it, then add and subtract.

(16/2)² = 8² = 64

x² + 16x + 64 − 64 + 8

x² + 16x + 64 − 56

(x + 8)² − 56

The vertex is (-8, -56).
