bonjour
Factoriser les expressions suivantes.
A=(x+3)(2x-4)-(4x+7) (2x-4)
A = (2x - 4)(x + 3 - 4x - 7)
A = 2(x - 2)(-3x - 4)
B=(5x+3)(X* - 3) + ( 5x+3) (4x - 5) ??
B = (5x + 3)(x - 3 + 4x - 5)
B = (5x + 3)(5x - 8)
C=(x+3)(4x +3)-x-3 ??
C = (x + 3)(4x + 3) - (x + 3)
C = (x + 3)(4x + 3 - 1)
C = (x + 3)(4x + 2)
C = (x + 3) * 2(2x + 1)
C = 2(x + 3)(2x + 1)
