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)
