Solution for (x-5)2/3=64 equation:


x in (-oo:+oo)

((x-5)^2)/3 = 64 // - 64

((x-5)^2)/3-64 = 0

((x-5)^2)/3+(-64*3)/3 = 0

(x-5)^2-64*3 = 0

x^2-10*x-167 = 0

x^2-10*x-167 = 0

x^2-10*x-167 = 0

DELTA = (-10)^2-(-167*1*4)

DELTA = 768

DELTA > 0

x = (768^(1/2)+10)/(1*2) or x = (10-768^(1/2))/(1*2)

x = (16*3^(1/2)+10)/2 or x = (10-16*3^(1/2))/2

(x-((10-16*3^(1/2))/2))*(x-((16*3^(1/2)+10)/2)) = 0

((x-((10-16*3^(1/2))/2))*(x-((16*3^(1/2)+10)/2)))/3 = 0

((x-((10-16*3^(1/2))/2))*(x-((16*3^(1/2)+10)/2)))/3 = 0 // * 3

(x-((10-16*3^(1/2))/2))*(x-((16*3^(1/2)+10)/2)) = 0

( x-((10-16*3^(1/2))/2) )

x-((10-16*3^(1/2))/2) = 0 // + (10-16*3^(1/2))/2

x = (10-16*3^(1/2))/2

( x-((16*3^(1/2)+10)/2) )

x-((16*3^(1/2)+10)/2) = 0 // + (16*3^(1/2)+10)/2

x = (16*3^(1/2)+10)/2

x in { (10-16*3^(1/2))/2, (16*3^(1/2)+10)/2 }
