Question

(x3-1)/(2x2-2x+2) : (7x2+7x+7)/(7x3+7) =dividir
​

Answer 1

Respuesta:

$\frac{\frac{\frac{ \textnormal{x3} - 1 }{ \left( 2 \times \textnormal{x2} \right) - \left( 2 \times x \right) + 2 }}{ \left( 7 \times \textnormal{x2} \right) + \left( 7 \times x \right) + 7 }}{ \left( 7 \times \textnormal{x3} \right) + 7 }$

$=$

$\frac{ - 1 + \textnormal{x3} }{ 14 \times \left( \left( \left( 1 - x + \textnormal{x2} \right) \times \left( 1 + x + \textnormal{x2} \right) \right) \times \left( 7 + \left( 7 \times \textnormal{x3} \right) \right) \right) }$
