It has become somewhat fashionable to have students derive theQuadratic Formulathemselves; this is done by completing the square for the generic quadratic equationax2+bx+c= 0. While I can understand the impulse (showing students how the Formula was invented, and thereby providing a concrete exampl...
Completing the squareIf we try to solve this quadratic equation by factoring,x2 + 6x + 2 = 0 we cannot. Therefore, we will employ a method called completing the square. We will make the quadratic take the form of a perfect square trinomial: a2 + 2ab + b2 = (a + b)2 .This...
方法2: 完全平方法(completing the square) 什么是完全平方?把ax²+bx+c转换为a(x+p)²+q 如何变成完全平方的形式? 我们需要用到以下两个公式: x²+2dx=(x+d)²-d² x²-2dx=(x-d)²-d² 用这两个公式我们就可以快速有效的把一般二次式转换为完全平方式啦,接下来我们可以通过一个例...
