The answer is not correct at all, that's a serious mistake in fact !

Well, I do not think that it is not correct as I tend to simplify first, then we have (x-1)*(x+3)>=0 and the Primes answer is ok. But a real bug is the fact that it even does that with simplify set to "None", here it should exclude 1.
