bonjour,

pouriez vous me factoriser :

D = (9x – 4)(2x + 1) + (9x – 4)²
E = (2x – 9)(x – 7) + (2x – 9)
F = (7x + 1)(4 – 2x) – (5 – x)(1 + 7x)

Bonjour,

Factoriser:

D = (9x – 4)(2x + 1) + (9x – 4)²

D= (9x-4)(2x+1+9x-4)

D= (9x-4)(11x-3)

E = (2x – 9)(x – 7) + (2x – 9)

E= (2x-9)(x-7+1)

E= (2x-9)(x-6)

F = (7x + 1)(4 – 2x) – (5 – x)(1 + 7x)

F= (7x+1)(4-2x-5+x)

F= (7x+1)(-x-1)

F= - (7x+1)(x+1)
