How to solve for a quadratic equation
WebSolving quadratic equations by completing the square Consider the equation x^2+6x=-2 x2 +6x = −2. The square root and factoring methods are not applicable here. [Why is that so?] But hope is not lost! We can use a method called completing the square. Let's start with the solution and then review it more closely. WebNow we can solve a Quadratic Equation in 5 steps: Step 1 Divide all terms by a (the coefficient of x2 ). 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.
