Solution for x^2+4x=6^(1/2) equation: 


x in (-oo:+oo)

x^2+4*x = 6^(1/2) // - 6^(1/2)

x^2+4*x-6^(1/2) = 0

x^2+4*x-6^(1/2) = 0

DELTA = 4^2-(1*4*(-6^(1/2)))

DELTA = 16-4*6^(1/2)

DELTA = 6.20204104

DELTA > 0

x = ((16-4*6^(1/2))^(1/2)-4)/(1*2) or x = (-(16-4*6^(1/2))^(1/2)-4)/(1*2)

x = ((16-4*6^(1/2))^(1/2)-4)/2 or x = (-((16-4*6^(1/2))^(1/2)+4))/2

x in { (-((16-4*6^(1/2))^(1/2)+4))/2, ((16-4*6^(1/2))^(1/2)-4)/2 }
