Explications étape par étape

Bonjour

Factoriser :

D = -(9x - 7) - (9x - 7)(-4x + 10)

D = -(9x - 7)(1 - 4x + 10)

D = -(9x - 7)(-4x + 11)

D = (9x - 7)(4x - 11)

E = 25 - (10x + 3)^2

E = 5^2 - (10x + 3)^2

E = (5 - 10x - 3)(5 + 10x + 3)

E = (-10x + 2)(10x + 8)

E = 2(-5x + 1) * 2(5x + 4)

E = 4(-5x + 1)(5x + 4)

F = -(9x + 8)(3x - 4) - (-6x + 5)(9x + 8)

F = -(9x + 8)(3x - 4 - 6x + 5)

F = -(9x + 8)(-3x + 1)

F = (9x + 8)(3x - 1)
