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)

Question
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)
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)
