Question

Does the expression x^3-1/x^2-1 simplify to x?

Answer 1

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

( x - 1 )s simplifies

`\frac{ {x}^(2) + x + 1 }{x + 1} \\`

_________________________________

Thus ; the expression doesn't simplify to x.

Answer 2

no it doesn't
