expression 8x squared + 4 or ,
in the vertex form is
.
<u>Step-by-step explanation:</u>
Here we have , to convert expression 8x squared + 4 or ,
in the vertex form . Let's find out:
Let
,
⇒ 
Comparing this equation with
we get ;

Now , We know that the vertex form of a parabola is ;
⇒
............(1)
Substitute the values of a and b into the formula
⇒ 
Now , Value of e is ;
⇒ 
⇒ 
Putting value of a, d ,e in equation (1) we get ;
⇒
⇒ 
Therefore , expression 8x squared + 4 or ,
in the vertex form is
.
