Explanation:

vertex form is

y = (x - h)² + k

with (h, k) being the vertex.

this is with the multiplications done

y = x² - 2hx + h² + k

and now we compare this to our original equation

y = x² - 10x + 14

-10x = -2hx

-10 = -2h

h = 5

h² + k = 14

25 + k = 14

k = -11

the vertex form is

y = (x - 5)² - 11

and for

y = x² - 10x

h = 5

25 + k = 0

k = -25

the vertex form is

y = (x - 5)² - 25
