Form a perfect-square trinomial.y = x2 + 2x + [___] − 1− [___]
y = (x + [___])2 + [___]
y = 8(x2 + 4x + [___]) + 17 + [___]
To obtain the graph of y = x2 - 6, shift the graph of y = x2 up✔ downleftright
Write in vertex form.
Factor the perfect-square trinomial in y = (x2 + 2x + 1) − 1− 1.y = (x + [___])2 − 1 −1
Write in vertex form. y = 8(x + ⇒ 2)2 + ⇒ -15
Simplify.y = (x + 1)2 − [___]
y = 8(x + [___])2 + [___]
