Bonjour pouvez vous simplifier ces expressions A=x X 3 B=y X 0 C=2 X x X(-4) D=y X(-5)X(-y)X4 E=t X3 X(t X4+3) F=x X(-1) X4X x X0X(-x)

Réponse :

A = x x 3

A = 3x

B = y x 0

B = 0

C = 2 x x x (-4)

C = 2x x (-4)

C = -8x

D = y x (-5) x (-y) x 4

D = -5y x (-y) x 4

D = 5y x 4

D = 20y

E = t x 3 x (t x 4 + 3)

E = 3t x (4t + 3)

E = 12t² + 9t

F = x x (-1) x 4 x x x 0 x (-x)

F = -x x 4 x x x 0 x (-x)

F = -4x x x x 0 x (-x)

F = -4x² x 0 x (-x)

F = 0 x (-x)

F = 0
