Solution for (h-3/5)(h-3/5)=1/2 equation: 


h in (-oo:+oo)

(h-(3/5))*(h-(3/5)) = 1/2 // - 1/2

(h-(3/5))*(h-(3/5))-(1/2) = 0

(h-3/5)*(h-3/5)-1/2 = 0

(h-3/5)^2-1/2 = 0

(2*(h-3/5)^2)/2-1/2 = 0

2*(h-3/5)^2-1 = 0

2*h^2-12/5*h-7/25 = 0

2*h^2-12/5*h-7/25 = 0

2*h^2-12/5*h-7/25 = 0

DELTA = (-12/5)^2-(-7/25*2*4)

DELTA = 8

DELTA > 0

h = (8^(1/2)+12/5)/(2*2) or h = (12/5-8^(1/2))/(2*2)

h = (2*2^(1/2)+12/5)/4 or h = (12/5-2*2^(1/2))/4

(h-((12/5-2*2^(1/2))/4))*(h-((2*2^(1/2)+12/5)/4)) = 0

((h-((12/5-2*2^(1/2))/4))*(h-((2*2^(1/2)+12/5)/4)))/2 = 0

((h-((12/5-2*2^(1/2))/4))*(h-((2*2^(1/2)+12/5)/4)))/2 = 0 // * 2

(h-((12/5-2*2^(1/2))/4))*(h-((2*2^(1/2)+12/5)/4)) = 0

( h-((12/5-2*2^(1/2))/4) )

h-((12/5-2*2^(1/2))/4) = 0 // + (12/5-2*2^(1/2))/4

h = (12/5-2*2^(1/2))/4

( h-((2*2^(1/2)+12/5)/4) )

h-((2*2^(1/2)+12/5)/4) = 0 // + (2*2^(1/2)+12/5)/4

h = (2*2^(1/2)+12/5)/4

h in { (12/5-2*2^(1/2))/4, (2*2^(1/2)+12/5)/4 }
