Bonjour,
1)
a) 8x + 12 =
4 (2x + 3)
b) 15x + 10 =
5 (x + 2)
c) 30x - 12 =
2 (15x + 6)
d) - 7x - 28 =
- 7 (x + 4)
e) 3x² + 6x =
3x (x + 2)
f) 16x² + 20x =
4x (4x + 5)
2)
a) 14x + 7 =
7 (2x + 1)
b) 9x² - 6 =
3 (3x² - 2)
c) - 8x² + 12x =
4x (- 2x + 3)
d) 9x² + 9x =
9x (x + 1)
e) 10x² + 15x³ =
5x² (2 + 3x)

a/14x+7=7(2x+1)
b/9x²-6=3(3x²-3)
c/-8x²+12x=4x(2x+3)
d/9x²+9x=9x(x+1)
e/10x²+15x²=x²(10+15)
