Answer:
x=1 x=17
Step-by-step explanation:
x^2-16x+17=0
x^2-17x-x+17=0
x(x-17)-1(x-17)=0
(x-1)(x-17)=0
x=1 or x=17

Given : y = x² - 16x + 17
To Find : vertex
Solution:
y = x² - 16x + 17
dy/dx = 2x - 16
dy/dx = 0
=> 2x - 16 = 0
=> x = 8
d²y/dx² = 2 > 0
Hence Vertex is the minimum value point at x = 8
y = x² - 16x + 17
= 8² - 16(8) + 17
= -47
Vertex is ( 8 , - 47)
or
y = x² - 16x + 17
y = (x - 8)² - 64 + 17
=> y = (x - 8)² - 47
Vertex is (8 , - 47)
