Because there are x's but also x2's in this equation, there isn't just one variable we can get by itself. This means we need a new strategy for solving quadratic equations. While there are a few different ways to do this, the most basic is through factoring. While this way won't...
With quadratic equations, there can be up to two x values that make the equation true and there will only be one answer if the left hand side is already a perfect square. Three methods for solving quadratic equations are factoring, completing the square (square root method), and the ...
We do not have to graph our quadratic equations in order to solve them, instead we could use factoring and then apply the zero product property.If then either or or both.ExampleSolve the following equation by factoring:Either x is equal to zero or x-4 is equal to zero or both....

Solve a quadratic equation by completing the square. From your experience in factoring you already realize that not all polynomials are factorable. Therefore, we need a method for solving quadratics that are not factorable. The method needed is called "completing the square." ...
