Question

Factorize:
$x ^{3} + x ^{2} - \frac{1}{x^2} + \frac{1}{x ^{3} }$
​

Answer 1

Answer:

${x}^{3} + {x}^{2} - \frac{1}{ {x}^{2} } + \frac{1}{ {x}^{3} } \\ \\ \frac{ {x}^{6} + {x}^{5} - x + 1 }{ {x}^{3} } \\ \\ \frac{ {x}^{5}(x + 1) -(x - 1) }{ {x}^{3} }$

Answer 2

Answer:  x^8+x^7+x^2

                   x^5+1    

Step-by-step explanation:

x^3+x^2 -      1          

                 x^2+    1  

                           x^3

=  x^8+x^7+x^2  

        x^5+1
