Question

x-1/2 =-1 find x²+1/x²
please answer this. ​

Answer 1

$x - \frac{1}{2} = - 1 \\ x = - 1 + \frac{1}{2 } \\ x = - \frac{1}{2} \\ = {x}^{2} + \frac{1}{ {x}^{2} } \\ x = - \frac{1}{2} \\ = { \frac{ - 1}{2} }^{2} + \frac{1}{ { \frac{ - 1}{2} }^{2} } \\ = \frac{1}{4} + 4 \\ = \frac{1 + 16}{4} \\ = \frac{17}{4}$
