x² + 2x +1 ≥ 0

Igualamos el polinomio del primer miembro a cero y resolvemos la ecuación

x² + 2x +1 = 0

a= 1

b= 2

c= 1

Aplicamos la resolvente.

Obtenemos una raíz doble. Factorizamos:

(x + 1)² ≥ 0

Como un número elevado al cuadrado es siempre positivo la solución es los reales.

x² + x +1 > 0

Igualamos el polinomio del primer miembro a cero y resolvemos la ecuación

x² + x + 1 = 0

a= 1

b= 1

c= 1

Aplicamos la resolvente.

Cuando no tiene raíces reales, le damos al polinomio cualquier valor, por

ejemplo x = 0

0² + 0 +1 > 0

Como se cumple la desigualdad, la solución es los reales.
