What is f(x)=8x2+4x written in vertex form

Vertex form:

Step-by-step explanation:

Given:

We need to write in vertex form.

Vertex form:

vertex: (h,k)

Step 1: Take out 8 common from each term

Step 2:  Add and subtract square of half of coefficient of x

Step 3: Factor the term inside parentheses

Hence, The vertex form of f(x)

x=25?

i think this is the answer hope this

step-by-step explanation:
