 =  >    \sqrt{ \frac{x}{x - 3} }  +  \sqrt{ \frac{x - 3}{x} }  =  \frac{5}{2} is \: not \: equal \: to \: 0 \: and \: 3

\blue{LET,}

  \orange{\sqrt{ \frac{x}{x - 3} }  = t}

t +  \frac{1}{t}  =  \frac{5}{2}

 \pink{ {t}^{2}  + 1} = \purple{ \frac{5}{2} }

 \mathbf \green{ 2 {t}^{2}  - 5t + 2 = 0}

 \mathfrak \red { 2 {t}^{2} (t - 2) - 1(t - 2)} = 0

(2t - 1)(t - 2) = 0

t =  \frac{1}{2}  \:  \: or \:  \:  \: 2

 \sqrt{ \frac{x}{x - 3} }  =  \frac{1}{2}  \:  \:  \:  \:  \:  \:  \: or \:  \:  \sqrt{ \frac{x}{x - 3} }  = 2

 \mathtt{\pink{\frac{x}{x - 3}  =  \frac{1}{4}}  \:  \:  \:  \: or \:  \:  \:  \:   \blue{ \frac{x}{x - 3}  = 4}}

4x = x - 3 \:  \:  \:   \:  \:  \:  \: \:  \: x = 4x - 12

There, are two values of x as below:-

x= -1 x=4
