WebLets suppose you could add the ± on both sides of the equation. This would create 4 possibilities: (x-4) = 10, (x-4)=-10, - (x-4)=10 and - (x-4)=-10. Looking at the second 1, divide by negative 1 to get (x-4)=-10 and you are back at the second one. Doing the same thing on the 4th, you get (x-4)=10 which is the same as the first. WebStep 1: Move the constant term to the right side of the equation. Step 2: Divide both sides of the equation by a if a is not 1. Otherwise, skip to step 3. Step 3: Complete the square: take the...
WebSolve a Quadratic Equation by Completing the Square. Not all quadratic equations can be factored or solved in their original form using the square root property. In these cases, we may use a method for solving a quadratic equation known as completing the square. Using this method, we add or subtract terms to both sides of the equation until we ...
