WebStep-by-step solution. Solving quadratic equations by completing the square. 1. Find the coefficients. To find the coefficients, use the standard form of a quadratic equation: 2. Make the a coefficient equal 1. Because , divide all coefficients and constants on both sides of the equation by : Simplify the expression. WebExample 1: perfect square. Find the closest perfect square by dividing the coefficient of x by 2. The coefficient of x is 8, so when we divide this by 2, we get 4. 2 Expand the perfect square expression. 3 Compare the constant term in the perfect square to the original expression, and adjust as needed.
WebCompleting the square is a technique for rewriting quadratics in the form (x+a)^2+b (x +a)2 +b. For example, x^2+2x+3 x2 +2x +3 can be rewritten as (x+1)^2+2 (x +1)2 +2. The two expressions are totally equivalent, but the second one is nicer to work with in some … WebCompleting the square is a method used to solve quadratic equations.
