Solve this simple equation on HP Prime

HP Recommended
HP Prime

Just getting to know this great calculator. Having issues with this simple equation, and how to solve (shorten) it, keeps getting error message in CAS mode.

 

2(2a+3b)-(5b+2a)+5

 

No problem for my Ti-nspire cx cas, but cannot figure out how to proper enter this into the HP Prime.

It's not picking up on the implicit multiplication with the '2' and the '('. Drop a '*' in there and it should work fine.

Enter: 2*(2a+3b)-(5b+2a)+5

You may have to press Simplify.

Enjoy your calculator!

Hi!, @whc4u:

 

Welcome, to HP Forum !. :generic:

 

In CAS Mode ...

2*(2*a+3*b)-(5*b+2*a)+5

 

If simplify ...

simplify(2*(2*a+3+b)-(5*b+2*a)+5) = 2*a+b+5

Kind Regards !.
Have a nice day !.
