The first three steps in writing f(x) = 40x + 5x2 in vertex form are shown.
Write the function in standard form. f(x) = 5x2 + 40x
Factor a out of the first two terms. f(x) = 5(x2 + 8x)
Form a perfect square trinomial. (eight-halves) squared = 16
f(x) = 5(x2 + 8x + 16) β 5(16)
What is the function written in vertex form?
f(x) = 5(x + 4) β 80
f(x) = 5(x + 8) β 80
f(x) = 5(x + 4)2 β 80
f(x) = 5(x + 8)2 β 80
