Sagot :
A = (4x+2)(2x-3)+(2x-3)(x-2)
= (8x²-12x+4x-6)+(2x²-4x-3x+6)
= 8x²-12x+4x-6+2x²-4x-3x+6
= 10x²-15x
= (8x²-12x+4x-6)+(2x²-4x-3x+6)
= 8x²-12x+4x-6+2x²-4x-3x+6
= 10x²-15x
A=(4x+2)(2x-3)+(2x-3)(x-2)
A = (8x² -12x +4x -6) + ( 2x² - 4x -3x +6)
A = 8x² -8x - 6 +2x² -7x +6
A = 10x² -15x
A = (8x² -12x +4x -6) + ( 2x² - 4x -3x +6)
A = 8x² -8x - 6 +2x² -7x +6
A = 10x² -15x
