1) A = (-3x+6)(7x-4)-(-3x+6)(x-5)
= -3x × 7x -3x × (-4) + 6 × 7x + 6×4 +3x × x +3x × (-5) - 6 × x - 6 × 5
= -21x² +12x + 42x + 24 + 3x² -15x -6x -30
= -18x² + 33x -6
2) A = (-3x+6)(7x-4)-(-3x+6)(x-5)
= (-3x+6)[(7x-4)-(x-5)]
= (-3x+6)(7x-4-x+5)
= (-3x+6)(6x+1)
3) A = (-3×(-2)+6)(7×(-2)-4)-(-3×(-2)+6)(-2-5)
= 12×(-18)+12×(-7)
= -132
pour le 3) je suis pas sur que c'est juste

1) A=(-3x+6)(7x-4)-(-3x+6)(x-5)
A=-21x²+12x+42x-24-(3x²+15x+6x-30)
A=-21x²+3x²+54x-21x-24+30
A=-18x²+33x+6
2) A=(-3x+6)[(7x-4)-(x-5)]
A=(-3x+6)(6x+1)
3) Si x=-2 ⇒ A=(-3*(-2)+6)(6*(-2)+1)
A=12*(-11)=-132
