Not a Problem
Bonjour tout le monde
Dans Calcul formel
Quand je veux écrire
√(x+2+3√(2x-5))+√(x-2-√(2x-5))=2√(2)
Geogebra affiche 2√(2)=2√(2)
Merci d'avance

Bonsoir, je confirme si on ne choisit pas le menu "Conserver la saisie" sinon c'est OK
if you graph sqrt(x+2+3 sqrt(2x-5))+sqrt(x-2-sqrt(2x-5)) you can see that the equation have an interval of solutions [2.5,3] with the machine precision
GG has not implemented equations with infinite number of solutions
wolfram alpha calculates
so for a computer the function gives 2 sqrt(2) in interval
in fact, it is not possible to program algebraic solutions for all equations

what means
wolfram alpha answers 2.5<=x<=3
Is d_0 all numbers from -1 to 1?
