A = 10 ( x + y )
B = 5 ( x + 3 )
C = 3 ( x + 2 y )
D = x ( x + 2 )
E = t ( 5 t + 4 )
F = 4 ( 6 y + 4 n² )
Explications étape par étape :
Bonjour
A = 10x + 10y
A = 10 (x + y)
B = 5x + 15
B = 5 (x + 3)
C = 3x + 6y
C = 3 (x + 2y)
D = x² + 2x
D = x (x + 2)
E = 5t² + 4t
E = t (5t + 4)
F = 24y + 16n²
F = 8 (3y + 2n²)
