xy + xy = x(x+y) + y(x+y)

J'ai commis la meme erreur !!
Je crois qu'elle doit faire :
xy + xy = x(x+y) + y(x+y)
(x+y) (x+y) = (3√2-4)(3√2-4)
18-16 =2 ! :D
Et pour la 2eme,
x+y = (x+y) - 2xy
(3√2+4)-2(3√2-4) = 18+16+24√2-6√2+8
42+18√2 ... N'est-ce pas ?? :)

Ah, d'accord j'ai compris:
x^2 y + x.y^2=xy(x+y)=18-16=2

x^2. y^2= (x+y)^2 -2xy= 18+16-6radical de 2 +8= 42-6radical de 2

C'est correcte ?

maria,
qui vous a dit que x = 3 radicale de 2 et que y = 4 ?
pour le deuxieme calcul, factorisez l'expression puis continuez....
j'attends votre reponse.
