bonjour
il faut deviner la consigne !
5a + 5b = 5.( a + b )
4a - 8c = 4 ( a - 2 c )
18a + 24b = 6 ( 3 a + 4 b )
12ac - 9ab = 3 a ( 4 c - 9 b )
5ab + 15ac = 5 a ( b + 3 c )
45xy - 5x = 5 x ( 9 y - 1 )
36a + 12 = 12 ( 3 a + 1 )
- 20a - 15b = - 5 ( 4 a + 3 b )
2b + 8b² = 2 b ( 1 + 4 b )
a² - 4a = a ( a + 4 )
6a² - 15ab = 3 a ( 2 a - 5 b )
7b - 7b² = 7 b ( 1 - b )
21a²b + 35a = = 7 a ( 3 a b + 5 )
4x² - 6x² = 2 x² ( 2 - 3 ) = 2 x² ( - 1 )
12a + 35ab = a ( 12 a + 35 b )
= 12bx - 20x = 4 x ( 3 b - 5 )
2x² + 6xy = 2 x ( x + 3 y )
14y² + 70xy³ = 7 y² ( 2 + 10 xy )
10b² - 100b⁵ = 10 b² ( 1 + 10 b ³)
36ab - 60b = 12 b ( 3 a - 5 )
