Calcul littéral
Réduire ou simplifier
7x + 15x = 22x
3x * 5x= 15x²
12x-7=
x = 1.x x+x=2x x*x=x²
Factoriser
C'est transformer une somme en un produit.
Mise en évidence : ka+kb=k(a+b) ka-kb=k(a-b)
Identités remarquables : a²+2ab+b²=(a+b)² a²-2ab+b²=(a-b)² a²-b²=(a-b).(a+b)
Développer
C'est transformer un produit en une somme.
Simple distributivité : k(a+b)=ka+kb k(a-b)=ka-kb
Double distributivité : (a+b)(c+d)=ac+ad+bc+bd
Identités remarquables : (a+b)²=a²+2ab+b² (a-b)²=a²-2ab+b² (a-b).(a+b)=a²-b²
Suppression de parenthèses
+(.....) -> rien ne change
5+(2x-7)=5+2x-7
-(.....) -> TOUS les signes à l'intérieur changent
5-(2x-7)=5-2x+7
