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).
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).
