Answer:

x -  \frac{3}{x}  = 2 \\  \\  {x}^{2} - 3 = 2x \\  \\  {x}^{2}   - 2x - 3 = 0 \\  \\  {x}^{2}  - 3x + x - 3 \\  \\ x(x - 3) + 1(x - 3) \\  \\( x + 1)(x - 3) \\  \\ take  \\ \: x + 1 = 0 \:  \: andx - 3 = 0 \\  \\ x =  - 1 \:  \:  \: x = 3 \\  \\ hence \: the \: value \: of \: x =  - 1 \: and \: 3

Step-by-step explanation:

x -  \frac{3}{x}  = 2 \\  \frac{ {x}^{2} - 3  }{x}  = 2 \\  {x}^{2}  - 3 = 2x \\  {x}^{2}  - 2x - 3 = 0 \\  {x}^{2}  -3x + x - 3 = 0 \\ ( {x}^{2}  - 3x) + (x - 3) = 0 \\ x(x   -  3) + 1(x  - 3)  = 0\\ (x - 3)(x + 1) = 0 \\ x =   3 \: or \: x = -1
