\(\dfrac{x-1}{x+2}\) - \(\dfrac{x}{x-2}\)= \(\dfrac{5x-2}{4-x^2}\) ĐKXĐ: x \(\ne\) \(\pm\) 2

<=> \(\dfrac{x-1}{x+2}\) + \(\dfrac{x}{2-x}\) = \(\dfrac{5x-2}{\left(x+2\right)\left(2-x\right)}\)

<=> \(\dfrac{\left(x+1\right)\left(2-x\right)}{\left(x+2\right)\left(2-x\right)}\) + \(\dfrac{x\left(x+2\right)}{\left(x+2\right)\left(2-x\right)}\) = \(\dfrac{5x-2}{\left(x+2\right)\left(2-x\right)}\)

<=> \(2x-x^2+2-x\) + \(x^2+2x\) = 5x-2

<=> 3x + 2 = 5x - 2

<=> 3x - 5x = -2 -2

<=> -2x = -4

<=> x = 2 (ko tm ĐKXĐ)
