Sagot :
Q = 4x -6x+10 = -2x+10
U = -18x²+12x+12x-8+10x² = -8x²+24x-8
E = 5x + (6+15x-4x-10x²)+4 = 5x+6+15x-4x-10x²+4 = -10x²x+20x+10
S = 8x-32-10x²+40+2x²+3 = -8x²+8x +11
J'orais besoin d'aide pour calculer les calcul a droite des letre Q,U,E,S
Q = 4x -6x+10 = -2x+10
U = -18x²+12x+12x-8+10x² = -8x²+24x-8
E = 5x + (6+15x-4x-10x²)+4 = 5x+6+15x-4x-10x²+4 = -10x²x+20x+10
S = 8x-32-10x²+40+2x²+3 = -8x²+8x +11
