Solution for (x-1)^2/5=4 equation:


x in (-oo:+oo)

((x-1)^2)/5 = 4 // - 4

((x-1)^2)/5-4 = 0

((x-1)^2)/5+(-4*5)/5 = 0

(x-1)^2-4*5 = 0

x^2-2*x-19 = 0

x^2-2*x-19 = 0

x^2-2*x-19 = 0

DELTA = (-2)^2-(-19*1*4)

DELTA = 80

DELTA > 0

x = (80^(1/2)+2)/(1*2) or x = (2-80^(1/2))/(1*2)

x = (4*5^(1/2)+2)/2 or x = (2-4*5^(1/2))/2

(x-((2-4*5^(1/2))/2))*(x-((4*5^(1/2)+2)/2)) = 0

((x-((2-4*5^(1/2))/2))*(x-((4*5^(1/2)+2)/2)))/5 = 0

((x-((2-4*5^(1/2))/2))*(x-((4*5^(1/2)+2)/2)))/5 = 0 // * 5

(x-((2-4*5^(1/2))/2))*(x-((4*5^(1/2)+2)/2)) = 0

( x-((2-4*5^(1/2))/2) )

x-((2-4*5^(1/2))/2) = 0 // + (2-4*5^(1/2))/2

x = (2-4*5^(1/2))/2

( x-((4*5^(1/2)+2)/2) )

x-((4*5^(1/2)+2)/2) = 0 // + (4*5^(1/2)+2)/2

x = (4*5^(1/2)+2)/2

x in { (2-4*5^(1/2))/2, (4*5^(1/2)+2)/2 }
