Find the product of x minus one by X Into X Plus One by X into x squared plus one by x square into x power 4 plus one by x power 4 is

Answer 1

$= x - \frac{1}{x} \times x + \frac{1}{x} \times {x}^{2} + \frac{1}{x {}^{2} } \times {x}^{4} + \frac{1}{x {}^{4} }$
$= x - 1 + x + {x}^{2} + \frac{1}{x {}^{4} }$
$= 2x - 1 + {x}^{2} + \frac{1}{x {}^{4} }$
$= \frac{2x {}^{5} - {x}^{4} - {x}^{6} + 1 }{x {}^{4} }$
