Solution for (u+2/11)2-242=0 equation: 


u in (-oo:+oo)

(u+2/11)^2-242 = 0

(u+2/11)^2-242 = 0

u^2+4/11*u-29278/121 = 0

u^2+4/11*u-29278/121 = 0

u^2+4/11*u-29278/121 = 0

DELTA = (4/11)^2-(-29278/121*1*4)

DELTA = 968

DELTA > 0

u = (968^(1/2)-4/11)/(1*2) or u = (-968^(1/2)-4/11)/(1*2)

u = (22*2^(1/2)-4/11)/2 or u = (-22*2^(1/2)-4/11)/2

(u-((-22*2^(1/2)-4/11)/2))*(u-((22*2^(1/2)-4/11)/2)) = 0

(u-((-22*2^(1/2)-4/11)/2))*(u-((22*2^(1/2)-4/11)/2)) = 0

( u-((-22*2^(1/2)-4/11)/2) )

u-((-22*2^(1/2)-4/11)/2) = 0 // + (-22*2^(1/2)-4/11)/2

u = (-22*2^(1/2)-4/11)/2

( u-((22*2^(1/2)-4/11)/2) )

u-((22*2^(1/2)-4/11)/2) = 0 // + (22*2^(1/2)-4/11)/2

u = (22*2^(1/2)-4/11)/2

u in { (-22*2^(1/2)-4/11)/2, (22*2^(1/2)-4/11)/2 }
