Solution for (w-7/2)^2=11 equation: 


w in (-oo:+oo)

(w-(7/2))^2 = 11 // - 11

(w-(7/2))^2-11 = 0

(w-7/2)^2-11 = 0

(w-7/2)^2-11 = 0

w^2-7*w+5/4 = 0

w^2-7*w+5/4 = 0

w^2-7*w+5/4 = 0

DELTA = (-7)^2-(1*5/4*4)

DELTA = 44

DELTA > 0

w = (44^(1/2)+7)/(1*2) or w = (7-44^(1/2))/(1*2)

w = (2*11^(1/2)+7)/2 or w = (7-2*11^(1/2))/2

(w-((7-2*11^(1/2))/2))*(w-((2*11^(1/2)+7)/2)) = 0

(w-((7-2*11^(1/2))/2))*(w-((2*11^(1/2)+7)/2)) = 0

( w-((2*11^(1/2)+7)/2) )

w-((2*11^(1/2)+7)/2) = 0 // + (2*11^(1/2)+7)/2

w = (2*11^(1/2)+7)/2

( w-((7-2*11^(1/2))/2) )

w-((7-2*11^(1/2))/2) = 0 // + (7-2*11^(1/2))/2

w = (7-2*11^(1/2))/2

w in { (2*11^(1/2)+7)/2, (7-2*11^(1/2))/2 }
