Bonjour!

Factoriser cette expression :

E=(5-4x)aucarré-(2x-1)(5-4x)

Sagot :

bjr

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

  = (5-4x) (5-4x - (2x-1))

  = (5-4x) (5-4x-2x+1)

  = (5-4x) (-6x + 6)

 = 6 (5-4x) (-x+1)

bonjour

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

E = ( 5 - 4 x ) ( - 6 x + 6 )

E = 6 ( 5 - 4 x ) (  - x + 1 )
