Salut à tous je suis nouveau et je suis en classe de 3ème. J'ai un petit problème au niveau des mathématiques . Voici certains calcul dont je n'arrive pas trop à comprendre :
Développer puis réduire les expressions suivantes :
A= -3(1-3x)
B= 2(x+y)-7(2x+3y)
C= 2(5+x)-(x-8)(7-6x)
Merci d'avance CIAO

A= -3 * 1 - (-3) 3x = -3 + 9x
B= 2x+2y -7*2x -7 * 3y = 2x+2y-14x-21y =-12x-19y
C=10+2x-( 7x-6x²-56+48x) = 10+2x-7x+6x²+56-48x = 66 -53x +6x²
