The method of completing the square is a useful algebraic technique. Within the South African school context, "completing the square" is most often used for three specific purposes: (i) solving quadratic equations, (ii) writing parabola equations in turning point format, and(iii) writing circle...
We begin by finding the constant d that can be used to complete the square. d=(b2)2=(122)2=62=36 x2+12x+d=0+d⇒ x2+12x+36=0+36⇒ (x+6)2=36 √(x+6)2=±√36 x+6=6orx+6=−6x=0x=−12 The completing the square method could of course be used to solve quadra...
