In Nepal, you are taught around the sixth grade that you can solve ax^2 + bx + c = 0 by splitting b into m and n such that mn = ac and m + n = b ( or m -n = b, if a and c have opposing signs). This "discovery" the author claims and some other corollaries were quite commonly known.
I find it absurd and, frankly, laughable that this is being heralded as something new!
