Hello, so you want to go ahead and write x squared plus 8 in vertex form.
00:04
We can basically think of this as set equal to 0.
00:06
We can move the constant to the right.
00:08
So we get x squared is equal to negative 8.
00:10
It's not going to complete the square.
00:12
Well, we just take half of the coefficient on the linear terms, since the coefficient, the quadratory term, is already 1.
00:19
While the linear term is actually 0, right? this is only an x squared term.
00:23
So the linear term, i guess it's 0.
00:25
X so what we can do well is just take half of zero is is still going to be zero and then if we square that we still get zero so we're basically adding zero to both sides so adding zero to both sides doesn't change anything so we still get x squared is equal to negative eight but then well x squared it can x squared be factored i guess x squared well, basically, this is already in, so vertex form, right? vertex form is the form a times the quantity, x minus h squared plus k...
