Bugs in Solve command.
Hello, I recently bought my HP prime and I am super happy with it, I think it is an extraordinary and complete and super fast machine. However it still has many bugs that I hope the following updates will be corrected. I have found the following bugs with the solve command:
1 The when I introduce solve(5x^22>=2x) and the CAS settings so: Exact and use radical with check and the options Complex and use i with not check the answer is x>= 1/5 * (1+sqrt(11) and dont show the other answer x<= 1/5 * (1sqrt(11). However, if I adjust CAS settings with the check on Complex, then the answer is x>= 1/5 * (1+sqrt(11) and 10>x. The first answer is incomplete and the second answer is incorrect. 2With solve((xa)*e^x=x*(xa),x) the calculator the HP Prime show undef, but in the other calculator of the competence, the nspire CX CAS the answer is e^x+x=0 or x=a in the exact mode, and x=a or x=0.567143 in the approximate mode.
