Bonjour ! ?

 

J'ai vraiment tout essayé pour réussir à résoudre ce QCM mais je bloque totalement...

On nous demande la dérivée de la fonction g(x) = 10x - [(5x^2-10)/(x^2+3)^2]; sachant que la réponse doit être g'(x)= [ 10x(x^2+3)-10x(x^2+3)+(5x^2-10)4x ] / (x^2+3)^3 

 

Si une âme charitable pouvait me développer le calcul ... 

Merci !
