Bonjour vous pouvez m'aidez s'il vous plaît 13 Ca3 Souligner le facteur commun puis factoriser.
A = 2x(x + 1) + 2x(8x + 5)
B = (x + 2)(3x + 4) + 3(x + 2)
C = (1 + 2x)(6x - 9) + (4x - 2)(6x - 9)
D = (6x + 6)(5x - 5) - (5x - 5)(4x – 4)
E = (4x - 3)2 + (2x + 7)(4x - 3)
F = (5x + 4)(2x - 3) - (5x + 4)
A = 2x(x + 1) + 2x(8x + 5)
B = (x + 2)(3x + 4) + 3(x + 2)
C = (1 + 2x)(6x - 9) + (4x - 2)(6x - 9)
D = (6x + 6)(5x - 5) - (5x - 5)(4x – 4)
E = (4x - 3)2 + (2x + 7)(4x - 3)
F = (5x + 4)(2x - 3) - (5x + 4)
