Explicación paso a paso:
[tex](x^{2})^{2} - 2 * x^{2} * -7+ -7^{2} \\[/tex] = x^4 +14x^2+49^+2x^2-14= x^4+16x^2+35
aplicamos la bicuadrada
t^2-14t+35
t= [tex]14+-\sqrt{(-14)^{2} -4* 1*35} /2\\[/tex]
[tex]14+-\sqrt{56} /2[/tex]
[tex]14+-7,48/2\\t^{2} = 17,74\\t^{2} =10,26[/tex][tex]t=\sqrt{17,74} = 4,21 \\t=\sqrt{10,26} = 3,20 \\[/tex]
