Finally, taking the square root and subtracting b/2a gives the solutions: x=-b/2a+-sqrt(-c/a+(b/2a)^2).How to Complete the Square? A quadratic equation is an equation of the form f(x)=ax2+bx+c (standard form). These equations have the highest power of x being x2, hence ...
The simplification that follows the previous step then leads to the solutions of the quadratic equation. The vertex of the quadratic equation can also be found when completing the square. Read How to Complete the Square | Method & Examples Lesson ...
Engineers use quadratic equations to design roller coasters! What Is a Quadratic Equation? In order to understand how to complete the square, you first have to know how to identify a quadratic equation. That’s because completing the square only applies to quadratic equations! In math, a quadra...
Here is a square whose side is a + b.It is composed of a square whose side is a, a square whose side is b, and two rectangles ab. That is,(a + b)2 = a2 + 2ab + b2.Now, here is how to complete a rectangle to make it a square...

Now you can complete the square. If the linear coefficient is 2r then you want to make the constant coefficient r2. Why? This is because of the fact that a2 + 2ra + r2 = (a + r)2 In your case, 2r = -2 so r = -2/2 = -1. Therefore we want the constant coefficient to...
