ITT we simplify (2x + 4) / (x^3 - 4x)
Should come out as 2 / (x^2 - 2x), but I can't just figure out how. Halp plx

I got that straight from the back of the math book. Oh well, wouldn't be the first time it fails.

(2x + 4) / (x^3 - 4x)
= 2(x + 2) / x(x^2 - 4)
= 2(x + 2) / x(x + 2)(x - 2)
= 2 / x(x - 2)
= 2 / (x^2 - 2x)

Actually, I should've put more brackets in there, but you know what I mean.
