Geogebra CAS only solves 1 of 2 solutions in this equation : 100=30*((1-(1+x)^(-4))/x)


Geogebra solves only x =-1.64 and not the other x= 0.11 ????


why ??


please help ASAP..

newest version 5.0.269


It apparently works if you use 2 lines as you do in your pic.

But will NOT work if you try to solve directly from line 1 ?
