\green{Answer}

x^2+1/x^2=2

Step-by-step explanation:

Quesion:

x+1/x=2

then evaluate

x^2+1/x^2

answer:

squaring both sides

(x +  \frac{1}{x} ) {}^{2}  = (2) {}^{2}

x {}^{2}  +  \frac{1}{x {}^{2} }  + 2(x)( \frac{1}{x} ) = 4

x {}^{2}  +  \frac{1}{x {}^{2} }   + 2 = 4

x {}^{2}  +  \frac{1}{x {}^{2} }  = 4 - 2

x {}^{2}  +  \frac{1}{x {}^{2} }  = 2
