Answer 1

Respuesta:

$\displaystyle{\implies x=15.41 \ \text{or} \ x=14.41}$

Explicación paso a paso:

$\displaystyle{x^2=x+222}\\\\\displaystyle{\implies x^2=x+222}\\\\\displaystyle{\implies x^2-x-222=0}\\\\\displaystyle{\implies x=\dfrac{1\pm\sqrt{(-1)^2+4\times1\times222}}{2} }\\\\\\\displaystyle{\implies x=\dfrac{1\pm\sqrt{889}}{2} }\\\\\\\displaystyle{\implies x=\dfrac{1\pm29.82}{2} }\\\\\\\displaystyle{\implies x=\dfrac{1+29.82}{2}=15.41 }\\\\\\\displaystyle{\implies x=\dfrac{1-29.82}{2}= 14.41}$
