Solving non linear systems

Hp prime

My Hp prime cant solve this system:

y=(x-3)^2*(1+y)

y=0.01+0.2*x

 

I tried solve, csolve, zeros and czeros but nothing works

Solving non linear systems

Hi !, @ Vinicius_adolfo
HP PRIME calculator perfectly solves your system of non-linear equations. Attached here is the CAS solution and the graphical solution (Advanced Graphing application). In this way, solve each equation. Advanced Graphing application is now the best graphic application in the world. You will not find a similar one in any other calculator.

Hi!, @Vinicius_adolfo :

You needed actualize the software in both calculator's, from ... ftp://ftp.hp.com/pub/calculators/Prime

But before, delete in the PC or Notebook, the previous version.

1) Firmware.

Open About HP Prime and check.

Too, verify the configuration of CAS if both are equal.

Solving non linear systems

Hi!, @Vinicius_adolfo
I read the information that your calculator does not provide solutions but empty parentheses. The problem is in the CAS settings. Here you have incorrectly set Exact. See it in the attached screenshot. Just change this setting and you will get good solutions. Don't worry. Now it's only going to get better.
