Problems in solving third degree inequalities and exponential equations.

[Jan 11]

Good day,

I would like to inform you that the latest firmware 2.1.14425 (2020 01 16) contains errors in solving third degree mathematical inequalities. It looks like this:

1. some inequalities are resolved very well and quickly (e.g. x ^ 2-3> x ^ 3-x)

2. some inequalities are solved for a very long time (e.g. x ^ 2-2> x ^ 3-x ^ 2-3x-6)

3. some cause disconnection of the calculator (e.g. x ^ 2-3x-2> x ^ 3)



I decided to check how the abovementioned inequalities are solved by the virtual calculator. He solves them very well, quickly and all.. I have an HP PRIME G1 calculator.
And one more thing. This applies to providing solutions to exponential equations. Solutions are given in complicated notation.
I will not describe it exactly, see it in the attached screenshot.
But here we have at least a system order. My calculator and virtual calculator give the same solutions.
I think this is a serious matter, it concerns elementary mathematical functions and should be solved as soon as possible.
