Step-by-step Solution
Para resolver la expresión dada:
\[
x = \frac { - \sqrt { 2 } \pm \sqrt { ( [ 2 ) ^ { 2 } - 4 ( \sqrt { 1 } ) ( \sqrt { - 3 } ) } } { 2 ( \sqrt { 1 } ) }
\]
Primero, simplificamos los términos:
1. \(\sqrt{1} = 1\), así que podemos reemplazar \(\sqrt{1}\) por \(1\).
2. Entonces, la expresión se convierte en:
\[
x = \frac { - \sqrt { 2 } \pm \sqrt { 2^2 - 4(1)(\sqrt{-3})} } { 2(1) }
\]
3. Calculamos \(2^2\):
\[
2^2 = 4
\]
4. Ahora, sustituimos en la raíz:
\[
x = \frac { - \sqrt { 2 } \pm \sqrt { 4 - 4\sqrt{-3} } } { 2 }
\]
5. Simplificamos el término dentro de la raíz:
\[
4 - 4\sqrt{-3} = 4(1 - \sqrt{-3}) = 4(1 - i\sqrt{3})
\]
6. Ahora, la expresión se convierte en:
\[
x = \frac { - \sqrt { 2 } \pm \sqrt { 4(1 - i\sqrt{3})} } { 2 }
\]
7. Sacamos la raíz cuadrada de \(4\):
\[
\sqrt{4(1 - i\sqrt{3})} = 2\sqrt{1 - i\sqrt{3}}
\]
8. Sustituyendo esto en la expresión de \(x\):
\[
x = \frac { - \sqrt { 2 } \pm 2\sqrt{1 - i\sqrt{3}} } { 2 }
\]
9. Dividimos cada término por \(2\):
\[
x = -\frac{\sqrt{2}}{2} \pm \sqrt{1 - i\sqrt{3}}
\]
Por lo tanto, la solución final es:
\[
x = -\frac{\sqrt{2}}{2} \pm \sqrt{1 - i\sqrt{3}}
\]
Quick Answer
La solución final es \( x = -\frac{\sqrt{2}}{2} \pm \sqrt{1 - i\sqrt{3}} \).
