Merci aux personnes qui m'aideront, c'est pour aujourd'hui. Exercice 4 : Développe puis réduis chaque expression.
A = 5(10x + 8) =
B = 9x(6 - 6x) =
C = 3(4x + 7) + 4(2x - 9) =
D == (5x + 8)(2r - 7) =
E = (2x - 5)(3x - 2) =
F = (4 + 7x)2 =
G= (3.x - 7)2 =
H= (3 + 4x)(4x - 3) =
A = 5(10x + 8) =
B = 9x(6 - 6x) =
C = 3(4x + 7) + 4(2x - 9) =
D == (5x + 8)(2r - 7) =
E = (2x - 5)(3x - 2) =
F = (4 + 7x)2 =
G= (3.x - 7)2 =
H= (3 + 4x)(4x - 3) =
