Find the vertex.

x^2+16x+8

vertex: (-8,-56).

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).

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).
