Question

Write g(x) = –16x + x2 in vertex form.

Write the function in standard form.
Form a perfect square trinomial by adding and subtractingStartFraction b Over 2 EndFraction squared .
Write the trinomial as a binomial squared.
Write the function is in vertex form, if needed.



g(x) = x2 – 16x
b = –16, so StartFraction negative 16 Over 2 EndFraction squared = 64
g(x) = (x2 – 16x + 64) – 64
g(x) = (x –
)2 –

Answer 1

Step-by-step explanation:

g(x) = x2 – 16x

b = –16, so StartFraction negative 16 Over 2 EndFraction squared = 64

g(x) = (x2 – 16x + 64) – 64

g(x) = (x – 2)
