When you complete the square, you change the equation so that the left side of the equation is a perfect square trinomial. That’s just a fancy way of saying that completing the square is a technique that transforms your quadratic equation from an equation that can’t be factored into one that can.

The act of "completing the square" involves taking half the coefficient of x in the quadratic x2 + ax and adding its square. But many students do not understand

Show Instructions In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`. Learning to Complete the Square. I remember learning how to “complete the square” as a teenager and I did what most students do, I memorized the steps. I was pretty good at memorization, so I The Corbettmaths Practice Questions and Answers to Completing the Square Our complete the square calculator is a free online tool that helps you solve quadratic equations using the completing the square method.

Given that most quadratic equations will not be Completing the square is a process that helps us rewrite a quadratic that's in the form ax2 + bx + c into the form a(x - h)2+k. So, why would we want to do this? (This is going to take a minute or two.) Completing incomplete squares: Background: The square of an expression of the form x+n or x−n is: (x+n)2=x2+2 nx+n2 The act of "completing the square" involves taking half the coefficient of x in the quadratic x2 + ax and adding its square. But many students do not understand Solve by Completing the Square To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b b . (b2)2=(5)2 The completing the square method can be used to factor any quadratic trinomial whatsoever. We assume that you have already read these sections: Factoring This makes solving a lot of equations easy. In fact, all quadratic equations can be solved by completing the square.

When you look at the equation above, you can see that it doesn’t quite fit … When you complete the square, make sure that you are careful with the sign on the numerical coefficient of the x-term when you multiply that coefficient by one-half. If you lose the sign from that term, you can get the wrong answer in the end because you'll forget which sign goes inside the parentheses in the completed-square form.
