bonjour
On donne a= -3 , b= 5 et c= -4.
F= 2a - 3b + c - ac et G = 2a - ( 3b + 5) ( 2c + 4 )
F = 2 *-3 - 3*5 + ( - 4) - ( - 3 * - 4 )
F = - 6 - 15 - 4 - ( 12 )
F = - 6 - 15 - 4 - 12
F = - 37
G = 2 * - 3 - ( 3 * 5 + 5 ) ( 2 * - 4 + 4 )
G = - 6 - ( 15 + 5 ) ( - 8 + 4 )
G = - 6 - ( 20 * - 4 )
G = - 6 - ( - 80 )
G = - 6 + 80 = - 74
