Mar 06, 2018 · 2. Solving Quadratic Equations by Completing the Square. For quadratic equations that cannot be solved by factorising, we use a method which can solve ALL quadratic equations called completing the square. We use this later when studying circles in plane analytic geometry.

Although completing the square is covered at GCSE, many students start the A level course with only a basic grasp of the method. Students often initially struggle in cases where \(a e 1\). However, the basics of the topic are very procedural in nature and can easily be grasped by the majority of students independently.
This formula can be derived from "completing the square'. In history, the earliest methods for solving this equation for explored as early as 2000 BC by the Egyptians and Babylonians, but was explored all over the world at different dates in history.
Multiply the length and width measurements to obtain the result, which will give you the total square feet of the wall or floor areas, e.g. if the floor-length is 14ft and width 10ft, multiply 14 by 10 so, your calculation will be 140 ft2.
This geometry calculator will take one known circle measurement (area, circumference, diameter, or radius) and calculate the other three. Plus, unlike other online circle calculators, this calculator will show its work and give a detailed, step-by-step explanation of the formulas and sequence used to arrive at each result.

As you can see, the x-coordinate of the vertex equals the number in brackets, but only up to change of signs. Furthermore, one sees from this calculation that you just have to use the binomial formula backwards: Build a binomial formula out of the function term. This does only work if there is the right number (the number completing the square).
