Completing the squareis a method that is used for converting a quadratic expression of the form ax2+ bx + c to the vertex form a(x - h)2+ k. The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression obtained...
Least square estimation consists of the method of projection, the method of derivative and the method of completing the squares. By comparing and analyzing the three methods, the conclusion has been drawn that the method of completing the squares is the best, as it provides the necessar...
The completing the square method could of course be used to solve quadratic equations on the form of ax2+bx+c=0 In this case you will add a constant d that satisfy the formula d=(b2)2−c Video lesson Solve the equation by completing the squares ...
When working with quadratic functions, three different methods can be used to solve for the variables in the functions. These methods are factoring, the quadratic formula, and completing the square. Each different method produces the same answer, but some methods are much simpler to use than ...
