Descomponer x^4+2*x^2+2 al cuadrado

Expresión a simplificar:

Solución

Ha introducido [src]
 4      2    
x  + 2*x  + 2
$$\left(x^{4} + 2 x^{2}\right) + 2$$
x^4 + 2*x^2 + 2
Expresión del cuadrado perfecto
Expresemos el cuadrado perfecto del trinomio cuadrático
$$\left(x^{4} + 2 x^{2}\right) + 2$$
Para eso usemos la fórmula
$$a x^{4} + b x^{2} + c = a \left(m + x^{2}\right)^{2} + n$$
donde
$$m = \frac{b}{2 a}$$
$$n = \frac{4 a c - b^{2}}{4 a}$$
En nuestro caso
$$a = 1$$
$$b = 2$$
$$c = 2$$
Entonces
$$m = 1$$
$$n = 1$$
Pues,
$$\left(x^{2} + 1\right)^{2} + 1$$
