[Bug] Simplify Command in Algebraic View
user6972 shared this problem 4 years ago
Define 3 numbers in Algebraic View as follows:
a = 2
b = 3
c = a + b
Then, in the input field, input:
The result obtained is f(x)=3x^2+2.
Why not f(x)=5x^2?
This result appears in GeoGebra Classic 5.0.482.0-d

Hmm, presumable a bug.
The reason is probably that GeoGebra reads for c*x² = a+b*x² but in CAS GeoGebra is doing right.
Fun fact: Simplify(c*b+a)=17 and not 13
Hmm, GeoGebra is inconsequent. ;-)
in CAS a=4 is an equation
please use a:=2
f(x):= c x^2

Haha! Thanks Noel! Both I and mathmagic are probably suffering for this awful heat wave that - in my case- is reducing my already little reasoning capabilities to the bare minimum.
Please try the new version (v486)
