**1. Homework Statement**

I need to know how to complete the square, I need to know how to do this to get

(this is to find the vertex of the quadratic function and the x intercept(s)

f(x)=aX

^{2}+bX+c to f(x)=a(x-h)

^{2}+k

It would be helpfull to see walkthroughs for when a=1 and when "a" does not equal 1.

questions:

-3x

^{2}+9x+(1/4)

and

x

^{2}-6x-2

**2. Homework Equations**

I dont think theres any, just that to get y set x=0 and to get x set y=0, for the intersepts that is.

h=horizontal shift in the graph

k=verticle shift in the graph

there is this shortcut too....

f(x)=a(x-h)

^{2}+k

and the vertex will be

((-b/2a),c-(b

^{2}/4a))

**3. The Attempt at a Solution**

Well, I'm learning this all out of school, and the book doesn't really explain how to do this very well, so I have no idea what do to. Could someone make walkthroughs on how to solve both of the question? This will help me tremendusly as I have been stuck on what to do now.
