# Solving quadratic equations by completing the square activities

Given a quadratic equation, the student will use tables to solve the equation. Now you've "completed the square" by creating a perfect square trinomial on the left side. The next step is to factor it. Remember, you can use the shortcut to factor it. Half of b will always be the number inside the parentheses. Once you've factored it, take the square root of both sides. Set up two separate equations and solve them separately. The method of “completing the square” offers an option for solving quadratic equations that are not factorable with integers alone (solutions may include fractions, radicals, or imaginary numbers). Step 1: Rearrange–Divide (as needed) Rearrange the equation, placing the constant term to the right of the equal sign and the variable terms Displaying top 8 worksheets found for - Solve Quadratic By Completing The Square.

Jun 02, 2015 · #3 Solving by Completing the Square. Before we solve equations by completing the square, we’ll learn how to complete the square with a quadratic expression. What the devil is ‘completing the square’? 𝑎𝑥2+𝑏𝑥+𝑐 𝑎𝑥+__2+__ It means putting a quadratic expressions in the form on the right, i.e. where 𝑥 only appears once. So that we can put that into practice, let me once again describe how to solve the quadratic. Let y=x+a/2. Then y satisfies a quadratic equation of the particularly simple form y 2 +C=0. Once we have solved this equation for y, it is easy to obtain a solution of the original equation for x, since x is a very simple linear function of y. Some of the worksheets below are Completing The Square Worksheets, exploring the process used to complete the square, along with examples to demonstrate each step with exercises like using the method of completing the square, put each circle into the given form, then determine the center and radius of each circle.Apr 02, 2020 · After taking the square root of both sides, you are left with x-3 = +/- 5. Next, to get x by itself, add 3 to both sides as follows. And to find your solutions, simply perform x = 3 + 5 AND x = 3 - 5 to get your answer as follows: Answer: x= 8 and x = -2. This method will apply to solving any quadratic equation! Lesson 5-5: Completing the Square. Home Teacher Pages ...
