x in (-oo:+oo)
(1/2)*x*(4*x-6)-3 = 0
1/2*x*(4*x-6)-3 = 0
1/2*x*(4*x-6)-3 = 0
2*x^2-3*x-3 = 0
2*x^2-3*x-3 = 0
2*x^2-3*x-3 = 0
DELTA = (-3)^2-(-3*2*4)
DELTA = 33
DELTA > 0
x = (33^(1/2)+3)/(2*2) or x = (3-33^(1/2))/(2*2)
x = (33^(1/2)+3)/4 or x = (3-33^(1/2))/4
(x-((3-33^(1/2))/4))*(x-((33^(1/2)+3)/4)) = 0
(x-((3-33^(1/2))/4))*(x-((33^(1/2)+3)/4)) = 0
( x-((3-33^(1/2))/4) )
x-((3-33^(1/2))/4) = 0 // + (3-33^(1/2))/4
x = (3-33^(1/2))/4
( x-((33^(1/2)+3)/4) )
x-((33^(1/2)+3)/4) = 0 // + (33^(1/2)+3)/4
x = (33^(1/2)+3)/4
x in { (3-33^(1/2))/4, (33^(1/2)+3)/4 }
