On donne : A = 6X - ( 5X + 4 ) B = (3X² -4 ) -( 3X - 2X² ) - 15 C = 7 (3X + 4 ) - 6 D = ( X - 4 ) ( 2X - 5 ) E = ( 3X - 4 )² F = (2X +5 ) ( 3X-1 ) +5 (X - 2 ) G = ( 3X - 5 ) (2X + 1 ) - ( 5X - 1 ) ( 4X- 3 ) REPONDER MOI SVP :)

A = 6x-5x-4 = x-4

B = 3x²-4-3x+2x² = 5x²-3x-4

c = 21x+28-6 = 21x +22

d = 2x²-5x-8x+20 = 2x² -13x+20

e = 9x² -24x +16 (identité remarquable)

f = 6x²-2x+15x+2 = 6x²+13x+2

g = 6x²+3x-10x-5 -20x²-15x +4x+3 = -14x² -18x -2
