Question

if x+1/x=3,find the value of : x^2+1/x^2​

Answer 1

$\huge{\mathcal{\blue{\underline{Answer}}}}$

Squaring both sides

$(x + \frac{1}{x} ) {}^{2} = 3 \\ x {}^{2} + \frac{1}{x {}^{2} } + 2(x)( \frac{1}{x} ) = 9 \\ x {}^{2} + \frac{1}{x {}^{2} } = 9 - 2 \\ x {}^{2} + \frac{1}{x {}^{2} } = 7$

Answer 2

$\huge\bold{ \dagger{ \mathrm {\blue{Answer...}}}}$

$\huge{\fbox{\fbox{\fbox{\fbox{\fbox{\fbox{\fbox{\fbox {\fbox{\fbox{7}}}}}}}}}}}$
