The steps in writing f(x) = 18x + 3x2 in vertex form are shown, but a value is missing in the last step.
write the function in standard form.
f(x) = 3x2 + 18x
factor a out of the first two terms. f(x) = 3(x2 + 6x)
form a perfect square trinomial.
f(x) = 3(x2 + 6x + 9) – 3(9)
write the trinomial as a binomial squared. f(x) = 3(x + – 27
what is the missing value in the last step?
