Expresión del cuadrado perfecto
Expresemos el cuadrado perfecto del trinomio cuadrático
$$\left(x^{4} - x^{2}\right) + 3$$
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
$$a = 1$$
$$b = -1$$
$$c = 3$$
Entonces
$$m = - \frac{1}{2}$$
$$n = \frac{11}{4}$$
Pues,
$$\left(x^{2} - \frac{1}{2}\right)^{2} + \frac{11}{4}$$
