Answer 2

Answer:

\frac{1}{x - 3} + \frac{2}{x - 2} = \frac{8}{x} \\ \frac{(x -2) +2(x - 3) }{ (x - 3)(x - 2)} = \frac{8}{x} \\ \frac{3x - 8}{x {}^{2} - 5x + 6} = \frac{8}{x} \\ \frac{3x {}^{2} - 8x}{x {}^{2} - 5x + 6 } = 8 \\ 3x {}^{2} - 8x = 8x {}^{2} - 40x + 6 \times 8 \\ 8x {}^{2 } - 3x {}^{2} - 40x + 8x + 48 = 0 \\ 5x {}^{2} - 32x + 48 = 0

5x²-20x-12x+48=0

5x(x-4)-12(x-4)=0

(5x-12)(x-4)=0

x=12/5,4
