WebThe 4 methods for solving are: 1) Factoring. This does not work for all quadratics because not all are factorable. But, it is usually easier than other methods when it works. 2) Square root method. This also only works for some quadratics. Specifically, it can be used for any quadratics in the form of "x^2 = a number" or " (ax+b)^2 = a number" WebWatch this video to learn how to find the equation of a parabola given two points.
