bonjour
b (x) = - x ³ + 21 x² /2 + 24 x
B (5 ) = - (5)³ + (21 * 5² ) /2 + 24 * 5
B ( 5 ) = - 125 + 525 /2 + 120 = 257.5 (en milliers €)
B ( 10) = - 10³ + ( 21 * 100 ) /2 + 24 * 10 = - 1 000 + 1 050 + 240 = 290
- x ³ + 21 x ²/2 + 24 x = 0
- 3 x² + 21 x + 24 x = 0
- 3 x² + 45 x = 0
- 3 x ( x - 15 ) = 0
x = 0 ou 15
