The term (b/2) 2 added to each side of the above equation is precisely the area of the missing corner, whence derives the terminology "completing the square". A variation on the technique. As conventionally taught, completing the square consists of adding the third term, v 2 to + to get a square. Completing the square is a technique for manipulating a quadratic into a perfect square plus a constant. The most common use of completing the square is solving …

Learn and revise how to solve quadratic equations by factorising, completing the square and using the quadratic formula with Bitesize GCSE Maths Edexcel. The following are general steps for solving a quadratic equation with a leading coefficient of 1 in standard form by completing the square. Example 3: Solve by completing the square: x 2 + 14 x + 46 = 0. Solution: Step 1: Add or subtract the constant term to obtain the equation in the form x 2 + b x = c. In this example, subtract 46 to move it

Complete the Square on a Polynomial - powered by WebMath This page will show you how to complete the square on a polynomial. Completing the square definition, a method, usually of solving quadratic equations, by which a quadratic expression, as x2 − 4x + 3, is written as the sum or difference of a perfect square and a constant, x2 − 4x + 4 + 3 − 4 = (x − 2)2 − 1, by addition and subtraction of appropriate constant terms.

Step 2 Move the number term (c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation. We now have something that looks like (x + p) 2 = q, which can be solved rather easily:

we can't use the square root initially since we do not have c-value. But we can add a constant d to both sides of the equation to get a new equivalent equation that is a perfect square trinomial. Remember that a perfect square trinomial can be written as Next, it will attempt to solve the equation by using one or more of the following: addition, subtraction, division, factoring, and completing the square. Use the following rules …
