if x²+1/x²=7 find the value of x+1/x​

Answer 1

Answer:

$x + \frac{1}{x} \\ on \: squaring \\ = > {(x + \frac{1}{x}) }^{2} = {x}^{2} + \frac{1}{ {x}^{2} } + 2 \\ = > {(x + \frac{1}{x} )}^{2} = 7 + 2 \\ = > {(x + \frac{1}{x} )}^{2} = 9 \\ = > x + \frac{1}{x} = \sqrt{9} \\ = > x + \frac{1}{x} = 3 \\ \\ \\ hope \: it \: helps \: you........ \\ \\ please \: mark \: my \: answer \: as \\ brainleist........$
