    Quadratics

    The technique of Completing-the square is explained in this session. 

    This is used to convert a quadratic in the form ax2 + bx + c to the completed-the-square form a(x - h)2 + k

    This technique is useful for solving certain quadratic equations and also for sketching quadratic curves

    The following concepts are discussed, with examples:

         ♦ Completing-the-square formula - How it works 

         ♦ 2 types of Quadratic Curves
     
         ♦ Coefficient of x2 term to determine nature of turning point of a quadratic curve
     
         ♦ Finding the turning point (h,k) of a curve by completing the square
     
         ♦ Sketching the Quadratic Curve, with examples
     
         ♦ Finding the coordinates of the intercepts with the coordinate axes
     
         ♦ Several examples to demonstrate completing-the square
     
         ♦ Past Exam Questions on Completing-the-square and Curve Sketching explained
