OK, here are some hints to help you along...

The correct
word is
declares. All code must be within a class, so you always need to create at least one. Most large applications can have hundreds if not thousands of classes.
3. Not sure what all of this specifically means yet. My best guess is that this let me do inputs.
Each class can have any number of methods. The main method is the one that the program will start executing (for most program types).
4. This is for "bx" in the equation. I don't know what parseDouble does, but I know args[0] is for my first input.
And your inputs are always strings. You can't do math on strings, so they need to be converted to a numeric type; in this case doubles.
7. I have no clue. What's with the 4.0? Why 4.0 instead of 4?
Most languages have a handful of different numeric types depending upon the nature of the numbers being represented. For the quadratic equation, integers won't do. 4 is an integer literal. 4.0 is a floating point literal.
I'll let you take it from here...
