f = (f1 f2) / (f1 + f2)

f(f1 + f2) = f1 f2

f f 1 + f f 2 = f1 f 2

f1 f2 - f f2 = f f1

f2 (f1 - f) = f f1

f2 = (f f1) / (f1 - f) <==== solution

Prove that for every two positive integers a and b that

Aleks [24]

$$(a+b)(\frac{1}{a}+\frac{1}{b}) \ \textgreater \ or = 4$
\\
1+a/b+b/a + 1 \geq 4
$ $$(a+b)(\frac{1}{a}+\frac{1}{b}) \ \textgreater \ or = 4$
$

distributed

choose 1 as your lowest positive integer

plug 1 into a and b

1 + 1 + 1 + 1 $\geq 4$
