1. Réponse pauloeldiablo
3x+6 = 3(x+2)
2a-4b = 2(a-2b)
(5x+1)((2x+3)+(5x+1)) -
2. Réponse Asiya38
3x+6 = 3(x+2)
2a-4b = 2(a-2b)
(5x+1)(2x+3) + (5x+1)(x+2) = (5x+1) [(2x+3) + (x+2)]
= (5x+1)(2x +3 +x +2)
= (5x+1)(3x+5)
(4x-5)(7x-1)-(4x-5)(3x+4) = (4x-5) [(7x-1) - (3x+4)]
= (4x-5)(7x -1 -3x -4)
= (4x-5)(4x-5)
