Question

x minus 1 by X + X + 1 by X + x square + 1 by x square​

Answer 1

Answer:

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