[Commentary:

On this page Harriot works with the multiplication from Add MS f. f. , namely,

(a - b) (a - c) (a + d)

, but now with the signs changed so that it becomes

(a + b) (a + c) (a - d)

. As in Add MS 6782 f. , he gives the special form of the equation that arises when

d = b + c

, when the term in

a a

vanishes. For a full derivation see Add MS 6783 F. (d.4). ]
