Solution for (x-2/7)^2-2(x-2/7)+37=o equation: 


x in (-oo:+oo)

(x-(2/7))^2-(2*(x-(2/7)))+37 = o // - o

(x-(2/7))^2-(2*(x-(2/7)))-o+37 = 0

(x-2/7)^2-2*(x-2/7)-o+37 = 0

(x-2/7)^2-2*(x-2/7)-o+37 = 0

x^2-o-18/7*x+32/49+37 = 0

x^2-o-18/7*x+1845/49 = 0

x^2-o-18/7*x+1845/49 = 0

x^2-o-18/7*x+1845/49 = 0

DELTA = (-18/7)^2-(1*4*(1845/49-o))

DELTA = 324/49-4*(1845/49-o)

324/49-4*(1845/49-o) = 0

(-4*49*(1845/49-o))/49+324/49 = 0

324-4*49*(1845/49-o) = 0

196*o-7056 = 0

(196*o-7056)/49 = 0

(196*o-7056)/49 = 0 // * 49

196*o-7056 = 0

196*o-7056 = 0 // + 7056

196*o = 7056 // : 196

o = 7056/196

o = 36

DELTA = 0  <=>  t_3 = 36

x = 18/7/(1*2) i o = 36

x = 9/7 i o = 36

( x = ((324/49-4*(1845/49-o))^(1/2)+18/7)/(1*2) or x = (18/7-(324/49-4*(1845/49-o))^(1/2))/(1*2) ) i o > 36

( x = ((324/49-4*(1845/49-o))^(1/2)+18/7)/2 or x = (18/7-(324/49-4*(1845/49-o))^(1/2))/2 ) i o > 36

o-36 > 0

o-36 > 0 // + 36

o > 36

x in { 9/7, ((324/49-4*(1845/49-o))^(1/2)+18/7)/2, (18/7-(324/49-4*(1845/49-o))^(1/2))/2 }
