Bonsoir
5x² - 8x² = - 3 x²
-5x - 8x = - 13 x
– 5x² + 8x² 4 x (6x - 4) = incomplet manque signe entre 8 x² et 4
-6x (4x + 4) = - 24 x² - 24 x
- 4 x (6x - 4) = - 24 x² + 16
6 x (4x - 4) = 24 x² - 24 x
2 x (6x + 7) = 12 x² + 14 x
6 x (4x + 4) = 24 x² + 24
4 x (6x + 4) = 24 x² + 16
5x - 8x = - 3 x
-5x2 - 8x2 = - 13 x²
-5x + 8x = 3 x
5x + 8x = 13 x
-4 X (6x + 4) = - 24 x - 16
5x X 8x = 40 x²
- 6x (44 - 4) = - 264 x + 24
