How many zero pairs must be added to the functionf(x) = x2 – 10x – 4 in order to begin writing the function in vertex form?

A.4
B.10
C.21
D.25

Answers

f(x) = x² - 10x - 4
f(x) + 4 = x² - 10x

- 10x / 2 = - 5x

- 5² = 25

f(x) + 4 + 25 = (x² - 10x + 25)
f(x) + 29 = (x-5)² 
f(x) = (x-5)² - 29

D. 25
