Completing the Square - Method, Formula, Examples - Cuemath
WebSome quadratic expressions can be factored as perfect squares. For example, x²+6x+9=(x+3)². However, even if an expression isn't a perfect square, we can turn it into one by adding a constant number. For example, x²+6x+5 isn't a perfect square, but if we add 4 we get (x+3)². This, in essence, is the method of *completing the square*. WebThis is called vertex form, and as the name implied it very easily lets you tell the vertex (the max or min of a parabola.) Specifically it is (-a, b) it is also much easier to get the 0s which would be +/- sqrt(-b) - a. not as easy as factored form of course. When it comes to graphing, vertex form is the easiest by far to recognize ... harbour grounds newsletter
