If it's not what You are looking for type in the equation solver your own equation and let us solve it.

Solution for 1/2(x^2-8x+8) equation:

x in (-oo:+oo)

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

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

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

x^2-8*x+8 = 0

x^2-8*x+8 = 0

DELTA = (-8)^2-(1*4*8)

DELTA = 32

DELTA > 0

x = (32^(1/2)+8)/(1*2) or x = (8-32^(1/2))/(1*2)

x = (4*2^(1/2)+8)/2 or x = (8-4*2^(1/2))/2

(x-((8-4*2^(1/2))/2))*(x-((4*2^(1/2)+8)/2)) = 0

1/2*(x-((8-4*2^(1/2))/2))*(x-((4*2^(1/2)+8)/2)) = 0

( x-((4*2^(1/2)+8)/2) )

x-((4*2^(1/2)+8)/2) = 0 // + (4*2^(1/2)+8)/2

x = (4*2^(1/2)+8)/2

( x-((8-4*2^(1/2))/2) )

x-((8-4*2^(1/2))/2) = 0 // + (8-4*2^(1/2))/2

x = (8-4*2^(1/2))/2

x in { (4*2^(1/2)+8)/2, (8-4*2^(1/2))/2 }
