E-Math - Quadratic Equations - Sketching Graphs using Completing the Squares

Topic: Quadratic Equations

You need to use completing the squares to modify the quadratic equation
before you sketch refer to my previous post completing the squares 1 and
 completing the square 2 if you need to revise.

When a Quadratic Graph is Positive i.e. x^2 -positive, it has a minimum
point, when it is Negative i.e. x^2 is negative, it has a maximum point.

I created this Blog after my students told me that there is very little information about how to solve GCE O Level Math and Additional Math (A-Math) questions on the internet. Even if they manage to find, the solution were for very basic questions. I am a Full-time Math Tutor in Singapore. I tutor mainly in Northern Singapore (Woodlands, Chua Chu Kang, Bukit Panjang, Yishun and Sembawang). I also tutor in Johor Bahru.
