possible de m'aider svp
FACTORISER B
B = (5x - 5)(7x + 3 ) - (2x -5)(5x-5)
rep = (5x - 5)(5x - 8 )
rep = (5x - 5)(5x + 8 )
rep = (5x - 5)(5x - 2 )
FACTORISER B
B = (5x - 5)(7x + 3 ) - (2x -5)(5x-5)
rep = (5x - 5)(5x - 8 )
rep = (5x - 5)(5x + 8 )
rep = (5x - 5)(5x - 2 )

Bonjour,
B=(5x-5)(7x+3)-(2x-5)(5x-5)
=(5x-5)((7x+3)-(2x-5))
=(5x-5)(7x+3-2x+5)
=(5x-5)(5x+8)
