Answer:

 \red {x^{2} + \frac{1}{x^{2}}}\green {= 23 }

Step-by-step explanation:

 Given \:x + \frac{1}{x} = 5 \: ---(1)

 We \: know \: that ,

\boxed { \pink {x^{2} + \frac{1}{x^{2}} =  \left( x + \frac{1}{x}\right)^{2} - 2}}

 = 5^{2} - 2\\= 25- 2\\= 23

Therefore.,

 \red {x^{2} + \frac{1}{x^{2}}}\green {= 23 }
