Question

Si x + 1/x = 11 . Calcular x^2 + 1/ x^2

Answer 1

Respuesta:

Explicación paso a paso:

x + 1/x = 11

( x + 1/x = 11 )²

x² + 2.x.1/x + ( 1/x )² = 11²

x² + 2 + 1/x² = 121

x² + 1/x² = 119

Answer 2

Respuesta:

x + 1/x = 11

( x + 1/x = 11 )²

x² + 2.x.1/x + ( 1/x )² = 11²

x² + 2 + 1/x² = 121

x² + 1/x² = 119
