What is the vertex form of f(x) = x2 + 6x + 3

Step-by-step explanation:

The equation of a parabola in Vertex form is:

Where is the vertex of the parabola

We can rewrite the function as:

 In order to convert it into vertex form we need to Complete the square:

Take the coefficient of the x term, divide it by 2 and square it:

Add and subtract 3² on the right side:

Now we must convert the right side to a squared expression, then we get:
