Yes, I know this one too
For 2nd degree polynomials, it means that any given polynomial
a^2+2ab+b^2 is equal to
(a+b)^2
Examples….
x^2+6x+9 is (x+3)^2
or x^2+20x+100 is (x+10)^2
or x^2+14x+49 is (x+7)^2

Actually, the log of a PRODUCT is the sum of the logs. Be careful.
logAB=logA+logB
The log of a RATIO is the difference of the logs.
log(A/B)=logA-logB
Memorization is all you need!

Two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one. In other words:
(a+b)/a=a/b=ᵠ
ᵠ has been […]
