Question

What is the vertex of the parabola given by y = x2 − 10x + 17?

Answer 1

-b/2a
10/2

Answer 2

a=1(from the x^2), b=-10, c=17

Answer 3

y= x^2 - 10x + 17

complete the square to find (h,k)

y= (x^2 -10x + _ ) - _ +17

y= (x^2 -10x + 25) - 25 + 17

factor out what's in the parentheses

y= (x-5)^2 - 8

and from here you can get your vertex (h,k)
(5,-8)
