Descomponer y^4-3*y^2+3 al cuadrado

Expresión a simplificar:

Solución

Ha introducido [src]
 4      2    
y  - 3*y  + 3
$$\left(y^{4} - 3 y^{2}\right) + 3$$
y^4 - 3*y^2 + 3
Expresión del cuadrado perfecto
Expresemos el cuadrado perfecto del trinomio cuadrático
$$\left(y^{4} - 3 y^{2}\right) + 3$$
Para eso usemos la fórmula
$$a y^{4} + b y^{2} + c = a \left(m + y^{2}\right)^{2} + n$$
donde
$$m = \frac{b}{2 a}$$
$$n = \frac{4 a c - b^{2}}{4 a}$$
En nuestro caso
$$a = 1$$
$$b = -3$$
$$c = 3$$
Entonces
$$m = - \frac{3}{2}$$
$$n = \frac{3}{4}$$
Pues,
$$\left(y^{2} - \frac{3}{2}\right)^{2} + \frac{3}{4}$$
