[Bug]-Missing root in solving equation
As following equation like this:
Quote:(x^2+x-1)^(x+3)=1
The correct answer is:-3,-2,-1,1,but Prime(Xcas) returned[-3 -2 1]
I tried it on different calculator/soft wear (like wolframalpha and CP400),but only a few can solve it correctly(Like nspire CX CAS...)
Almost all calculator/soft wear missing this root:'-1'
Do you guys want to have a try?I havn't test it on 50g XD
