Question

Halla un factor primo de:
2x elevado al cubo + 2x elevado al cuadrado - 2x - 2

Answer 1

Explicación paso a paso:

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