Bonjour,

A = 6b² - 15c

A = 3 (2b² - 5c)

B = 7a² + a

B = a (7a + 1)

C = 2a² - 3a

C = a (2a - 3)

D = 4a - 4m + 4d

D = 4 (a - m + d)

E = 20m³ - 5m² + 15m

E = 5m (4m² - m + 3)

F = 2b² - 6mb³

F = 2b2 (1 - 3mb)

Bonjour

Factoriser :

A = 6b^2 - 15c

A = 3 x 2b^2 - 3 x 5c

A = 3(2b^2 - 5c)

B = 7a^2 + a

B = a x 7a + a x 1

B = a(7a + 1)

C = 2a^2 - 3a

C = a x 2a - a x 3

C = a(2a - 3)

D = 4a - 4m + 4d

D = 4 x a - 4 x m + 4 x d

D = 4(a - m + d)

E = 20m^3 - 5m^2 + 15m

E = 5m x 4m^2 - 5m x m + 5m x 3

E = 5m(4m^2 - m + 3)

F = 2b^2 - 6mb^3

F = 2b^2(1 - 3mb)
