    Polynomania!

    factoring_polynomials_1
        Factor simple polynomaials of form Ax^2+Bx+C where A = 1
    
    solving_quadratics_by_factoring
        Modify existing deployed exercise to improve hints and simplify by
        ensuring A = 1
    
    solving_quadratics_by_factoring_2
        Same as above: improved hints; but A is not always 1 (sometimes it is)
        Basically the existing solving_quadratics_by_factoring exercise with
        better hints.
    
    factoring_difference_of_squares_1
        Factor difference of squares where A = 1
        Added coloring to hints making it easier to follow. Changed answer
        validation from AST to regex:
            - AST was not properly handling invalid input in some cases: unbalanced
            parentheses, for example.
            - AST was using 'custom' answer type which didn't display the guess in
            the timeline. Regex properly displays the guess in the timeline.
            - Answer format for these exercises is well-defined enough that there
            are no reasons not to validate with regex. AST can be improved in the
            future (add new AST answer type, better handling of malformed
            expressions, etc.) but doesn't seem ready yet.
    
    factoring_difference_of_squares_2
        Factor difference of squares where A != 1
        See above
