Which of the following are the coordinates of the vertex of y = x2 - 10x + 2?

y=x^2 - 10x + 2

Use the form ax^2 + bx + c to find the values of a, b, and c.

a = 1 (no number in front of the x^2)

b = 10

c = 2

Vertex form is a (x+d) ^2 + e

Solve for d using d = b/2a

d = 10 / 2

d = 5

Find e using e = c - b^2/4a

e = 2 - 10^2/4

e = 2 - 25

e = - 23

Vertex = d, e

Vertex = (5, - 23)
