bonjour
A = 4 x + 4 y = 4 ( x + y )
B = 6 x 9 + 6 x 3 = 6 ( 9 + 3 )
C = 8 a + 8 b = 8 ( a + b )
D = 5*3 + 3 *14 = 3 ( 5 + 14 ) = 3 ( 19 )
E = 2 + 2 x = 2 ( 1 + x )
F = 7 a + 7 = 7 (a + 1 )
G = 4 x² + 4 x = 4 x ( x+ 1 )
H = 6 y + 6 y² = 6 y ( 1 + y )
I = 3x² + 5 x = x ( 3 x + 5 )
j = 2 ab + b² = b ( 2 a + b )
