Bonjour, Quelqu'un peux vérifier mes calculs? 1/ Réduire
A = -13x²+5x-6+2x²-9x+4
A= -11x²-4x-2

2/ Développer et réduire
B = (x+3)(3x-1)-(1-4x)(x+6)
B= (3x²-x+9x-3)-(x+6-4x²-24x)
B = 3x²-x+9x-3-x-6+4x²-24x
B = 7x²-17x-9

3/ C = x(x+2)-((2(2x-4)+(8-5x))
C= x²+2x-(4x-8+8-5x)
C = x²+2x-4x+8-8+5x
C = x²+3x
