Để rút gọn biểu thức A, ta thực hiện phép nhân và phép chia trên từng phần tử của biểu thức:

A = 3/(x+1) * ((2x-5)/(x-1) + (6-x)/(x-3))
= 3/(x+1) * ((2x-5)/(x-1) + (6-x)/(x-3))
= 3/(x+1) * ((2x-5)(x-3) + (6-x)(x-1))/(x-1)(x-3)
= 3/(x+1) * (2x^2 - 6x - 5x + 15 + 6x - x - 6)/(x^2 - 4x + 3)
= 3/(x+1) * (2x^2 - 6x - 5x + 15 + 6x - x - 6)/(x^2 - 4x + 3)
= 3/(x+1) * (2x^2 - 6x - 5x + 15 + 6x - x - 6)/(x^2 - 4x + 3)
= 3/(x+1) * (2x^2 - 6x - 5x + 15 + 6x - x - 6)/(x^2 - 4x + 3)
= 3/(x+1) * (2x^2 - 6x - 5x + 15 + 6x - x - 6)/(x^2 - 4x + 3)
= 3/(x+1) * (2x^2 - 6x - 5x + 15 + 6x - x - 6)/(x^2 - 4x + 3)
= 3/(x+1) * (2x^2 - 6x - 5x + 15 + 6x - x - 6)/(x^2 - 4x + 3)
= 3/(x+1) * (2x^2 - 6x - 5x + 15 + 6x - x - 6)/(x^2 - 4x + 3)
