Completing The Square One of the most challenging topics to teach in high school mathematics is “Completing the Square.” This is because educators do not always fully understand the topic and because it includes several algebraic steps that are incredibly challenging for students. An eye-opening ...

Afterward, simplify the perfect square trinomial to successfully transform the function into the vertex form of that quadratic function.What does Completing the Square Mean? One of the most commonly used functions in mathematics is the quadratic function. When working with quadratic functions, three ...
In mathematics, we have a technique we can use to solve quadratic equations called completing the square. This technique makes use of the completing the square rule, which states that x2+bx+(b2)2=(x+b2)2, and it makes use of the square root property, which states that if M2 = N, ...
We've already introduced this method in our completing the square calculator, but it's always good to have a quick refresher, isn't it? OK. Completing the square is a method in mathematics (in algebra, to be precise) that we use to solve quadratic equations (or equivalently, to factor ...
Masters of Education Graduate with Mathematics Expertise About this tutor › In any quadratic, before you complete the square, you first divide through by the leading coefficient to make it 1. In your case of a2 - 2a - 8 = 0, the leading coefficient is already 1. Now you can complete...
B1. How can this topic be used in your students’ future courses in mathematics? Completing the square is a fairly nifty trick that pops up a decent bit in Calculus 2, particularly in taking integrals of trig functions. Since they need to be in the specific form of (x+a)^2, or some...
