Bonsoir,
4m + 6 + 8m² + 1 + 6m + 12 + 4m² + 9
= 8m² + 4m² + 4m + 6m + 6 + 1 + 12 + 9
= 12m² + 10m + 28
-4x - 6 + 12x² + 10 - 6x² + 12x + 4x + 9
= 12x² - 6x² - 4x + 12x + 4x - 6 + 10 + 9
= 6x² + 12x + 13
Bonsoir,
Simplifier:
E = 4m + 6 + 8m² + 1 + 6m + 12 + 4m² + 9
E = 8m² + 4m² + 4m + 6m + 6 + 1 + 12 + 9
E = 12m² + 10m + 28
F = -4x - 6 + 12x² + 10 - 6x² + 12x + 4x + 9
F = 12x² - 6x² - 4x + 12x + 4x - 6 + 10 + 9
F = 6x² + 12x + 13
Bonne soirée.
