Question

ifx+1/x=4, then the value of x²+x square=​

Answer 1

Answer:

$x + \frac{1}{x} = 4 \\ by \: squaring \: both \: sides \\ {x}^{2} + \frac{1}{ {x}^{2} } + 2 \times x \times \frac{1}{x} = 16 \\ or \: {x}^{2} + \frac{1}{ {x}^{2} } + 2 = 16 \\ or \: {x}^{2} + \frac{1}{ {x}^{2} } = 16 - 2 \\ or \: {x}^{2} + \frac{1}{ {x}^{2} } = 14$
