Solution for 1/2(-4)=(1/2x2)w equation: 


x in (-oo:+oo)

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

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

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

-1/2*w*x^2 = 2 // : -1/2*w

x^2 = -4*w^-1

x^2 = -4*w^-1 // ^ 1/2

abs(x) = (-4)^(1/2)*w^(-1/2)

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

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