Bonjour, quelqu'un pourrait m'aider pour ce devoir svp?
On donne : D = 14x² - 9x - 18.
Calculer la valeur de D pour x = 3/7 (donner le résultat sous forme d'une fraction la simple possible).
Merci

Salut,
D= 14 x (3/7)² - 9 x 3/7 - 18
D= 14 x 9/49 - 27/7 -18
D= 2 x 9/7 - 27/7 - 18
D= 18/7 - 27/7 - 18
D= -135/7
