Take the square root of both sides of the equation.Ĭompleting the square is particularly useful when the quadratic equation does not factor easily.Factor the left-hand side of the equation as a perfect square trinomial.Add this value to both sides of the equation. Divide the coefficient of x by 2 and square the result.Move the constant term to the right-hand side of the equation.If the coefficient of x^2 is not 1, divide both sides of the equation by a.

Rewrite the quadratic equation in the form ax^2 + bx + c = 0, where a, b, and c are constants.Here are the steps to solve quadratic equations by completing the square: It involves manipulating the equation to create a perfect square trinomial, which can then be easily factored. How to Solve Quadratic Equations by Completing the SquareĬompleting the square is a useful technique for solving quadratic equations. With practice, completing the square can become a valuable tool for solving quadratic equations quickly and efficiently. However, it can be a time-consuming process, and it is important to check the solution by plugging it back into the original equation to ensure that it is valid. Once the equation is in the form (x + p)^2 = q, where p and q are constants, the equation can be easily solved by taking the square root of both sides and solving for x.Ĭompleting the square is a powerful technique for solving quadratic equations, as it can be used to solve equations that cannot be solved by factoring or the quadratic formula. The constant term is determined by taking half of the coefficient of the x-term and squaring it. Then, the equation is transformed by adding and subtracting a constant term to create a perfect square trinomial. To solve a quadratic equation by completing the square, one must first rearrange the equation into the form ax^2 + bx + c = 0, where a, b, and c are constants. Completing the square is a technique that involves manipulating an equation to create a perfect square trinomial, which can then be easily solved. One common method of solving quadratic equations is by completing the square.
