bonjour
A = 7 x + 14
A = 7 ( x + 2 )
B = 8 y + 7 y
B = y ( 8 + 7 ) = y ( 15)
C = 6 ab + 5a
C = a ( 6 b + 5 )
D = 6 m - 9 m ²
d = 3 m ( 2 - 3 m)
F = ( 7 x + 5 ) ( 3 x + 2 + x - 9 )
f = ( 7 x + 5 ) ( 4 x - 7 )
G = ( 3 x - 5 ) ( x - 4 - 8 x - 7 )
G = ( 3 x - 5 ) ( - 7 x - 11 )
18 x² + 6 x = 6 x ( 3 x + 1 )
