Bonjour
Simplifier les expressions ci-dessous.
E=6 x (x + 7) + 58
E = 6x² + 42x + 58
F= 4 x (x + 8) + 6x
F = 4x² + 32x + 6x
F = 4x² + 38x
G= 18+4 x (x + 8)
G = 18 + 4x² + 32x
H= 12x + 3 x (x + 7)
H = 12x + 3x² + 21x.
H = 3x² + 33x.
Bonjour,
Simplifier :
Distributivité : K(A + B) = KA + KB
E = 6(x + 7) + 58
E = 6x + 42 + 58
E = 6x + 100
F = 4(x + 8) + 6x
F = 4x + 32 + 6x
F = 10x + 32
G = 18 + 4(x + 8)
G = 18 + 4x + 32
G = 50 + 4x
H = 12x + 3(x + 7)
H = 12x + 3x + 21
H = 15x + 21
Bonne journée.
