Add 16y on both sides of the equation
Notice that now the equation has the general form of a parabola
In this case
Add and subtract
on the right side of the equation
Factor the expression that is inside the parentheses
Divide both sides of the equality between 16
For an equation of the form
the vertex is: (h, k)
In this case
the vertex is:
