Question
Aidez moi silvousplait factorisez A= (3x+2) (x-5) + (3x +2 ) ( 2x + 1)
B= (4x-3 ) (2x +5) + (4x-3) (7x-1)
C= (5x - 2) (6x + 1) + (5x - 2) (4x - 9)
B= (4x-3 ) (2x +5) + (4x-3) (7x-1)
C= (5x - 2) (6x + 1) + (5x - 2) (4x - 9)

A = (3x+2) [(x-5)+(2x+1)]
A = (3x+2)(x-5+2x+1)
A= (3x+2) (3x-4)
B = (4x-3)[(2x+5)+(7x-1)]
B = (4x-3)(2x+5+7x-1)
B = (4x-3)(9x-4)
C = (5x-2)[(6x+1)+(4x-9)]
C = (5x-2)(6x+1+4x-9)
C = (5x-2)(10x-8)
