Answer:(-5,-7)

Step-by-step explanation:

Rewrite in Vertex form and use this form to find the vertex (h,k)

Answer:

y = (x + 5)² - 7

Step-by-step explanation:

Given

y = x² + 10x + 18

To obtain vertex form use the method of completing the square

add/ subtract ( half the coefficient of the x- term )² to x² + 10x

y = x² + 2(5)x + 25 - 25 + 18

  = (x + 5)² - 7 ← in vertex form
