Question

a³-b³ / a²-2ab+b² pls

Answer 1

Explicación paso a paso:

$\frac{{a}^{3} - {b}^{3} }{ {a}^{2} - 2ab + {b}^{2} }$

$= \frac{(a - b)( {a}^{2} + ab + {b}^{2} }{ {a}^{2} - 2ab + {b}^{2} } \\ = \frac{(a - b)( {a}^{2} + ab + {b}^{2} ) }{(a - {b}^{2} ) } \\ = \frac{(a - b)( {a}^{2} + ab + {b}^{2} ) }{(a - {b} )(a - {b}) } \\ = \frac{ {a}^{2} + ab + {b}^{2} }{(a - b)}$

Espero te sirva :)
