Solution for x^2-16/6x*7x/x+4 equation: 


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

x^2-((7*(16/6)*x*x)/x)+4 = 0

x^2+(-56/3)*x+4 = 0

x^2-56/3*x+4 = 0

DELTA = (-56/3)^2-(1*4*4)

DELTA = 2992/9

DELTA > 0

x = ((2992/9)^(1/2)+56/3)/(1*2) or x = (56/3-(2992/9)^(1/2))/(1*2)

x = ((2992/9)^(1/2)+56/3)/2 or x = (56/3-(2992/9)^(1/2))/2

x in { (56/3-(2992/9)^(1/2))/2, ((2992/9)^(1/2)+56/3)/2 }
