Solution for (x-1)^2/3=16 equation:


x in (-oo:+oo)

((x-1)^2)/3 = 16 // - 16

((x-1)^2)/3-16 = 0

((x-1)^2)/3+(-16*3)/3 = 0

(x-1)^2-16*3 = 0

x^2-2*x-47 = 0

x^2-2*x-47 = 0

x^2-2*x-47 = 0

DELTA = (-2)^2-(-47*1*4)

DELTA = 192

DELTA > 0

x = (192^(1/2)+2)/(1*2) or x = (2-192^(1/2))/(1*2)

x = (8*3^(1/2)+2)/2 or x = (2-8*3^(1/2))/2

(x-((2-8*3^(1/2))/2))*(x-((8*3^(1/2)+2)/2)) = 0

((x-((2-8*3^(1/2))/2))*(x-((8*3^(1/2)+2)/2)))/3 = 0

((x-((2-8*3^(1/2))/2))*(x-((8*3^(1/2)+2)/2)))/3 = 0 // * 3

(x-((2-8*3^(1/2))/2))*(x-((8*3^(1/2)+2)/2)) = 0

( x-((2-8*3^(1/2))/2) )

x-((2-8*3^(1/2))/2) = 0 // + (2-8*3^(1/2))/2

x = (2-8*3^(1/2))/2

( x-((8*3^(1/2)+2)/2) )

x-((8*3^(1/2)+2)/2) = 0 // + (8*3^(1/2)+2)/2

x = (8*3^(1/2)+2)/2

x in { (2-8*3^(1/2))/2, (8*3^(1/2)+2)/2 }
