System of inequalities (another error)
Hello everyone,
in this simple system of non-linear inequalities, the HP Prime gives the wrong result:
SOLVE({7x-x^2>0,x^2-6x-4<0}), it returns 0<x<3+sqrt(13).

The right result here is: 0<x<7 ;-)
This makes the Prime unreliable in doing such exercises.
Best,

Aries :-)
