.
All you need to do is to learn:


1.  What is the vertex ?


2.  What is the standard form ?


3.  What is the vertex form ?


4.  How to expand (x-4)^2 - 16 ?


5.  How to solve the quadratic equation using the quadratic formula ?


Learn it from your textbook. Tutors exist not for replacing a textbook for you.

For n.5 you can learn from the lessons
    - Introduction into Quadratic Equations
    - PROOF of quadratic formula by completing the square
in this site.

Good luck and happy learning.


I see a big desire from your side to seat on the tutor's neck, which is    V E R Y    bad.
