This is a Java Applet created using GeoGebra from www.geogebra.org - it looks like you don't have Java installed, please go to www.java.com

Which method is best to use for what kind of equation?
Is there any way to know what type of solution(s) you will have before solving?
What do the solutions tell you about the function?
