Solution for u^2-9u+20/3u^2+6u-105 equation: 


u in (-oo:+oo)

u^2+(20/3)*u^2-(9*u)+6*u-105 = 0

u^2+(20/3)*u^2-9*u+6*u-105 = 0

23/3*u^2-3*u-105 = 0

DELTA = (-3)^2-(-105*4*23/3)

DELTA = 3229

DELTA > 0

u = (3229^(1/2)+3)/(2*23/3) or u = (3-3229^(1/2))/(2*23/3)

u = 3/46*(3229^(1/2)+3) or u = 3/46*(3-3229^(1/2))

u in { 3/46*(3-3229^(1/2)), 3/46*(3229^(1/2)+3) }
