factorable trinomials

[Max Alekseyev]

SeqFans,

I've been reading archives of Scripta Mathematica circa 1940 and found
some curious (and well forgotten) math reports that may result to new
sequences in OEIS.
A particular one that has drawn my attention is about "factorable trinomials":

If anybody wants to elaborate on this topic and add new
references/sequences to OEIS - please do.

For references this particular report is from Scripta Mathematica
1943, 9(1), 59-60.

Regards,
Max
