Solution for 1/2x*1/3x+1/4x=13/12 equation: 


x in (-oo:+oo)

((1*(1/2)*x)/3)*x+(1/4)*x = 13/12 // - 13/12

((1*(1/2)*x)/3)*x+(1/4)*x-(13/12) = 0

(((1/2)*x)/3)*x+(1/4)*x-13/12 = 0

1/6*x^2+1/4*x-13/12 = 0

DELTA = (1/4)^2-(-13/12*1/6*4)

DELTA = 113/144

DELTA > 0

x = ((113/144)^(1/2)-1/4)/(1/6*2) or x = (-(113/144)^(1/2)-1/4)/(1/6*2)

x = 3*((113/144)^(1/2)-1/4) or x = -3*((113/144)^(1/2)+1/4)

x in { -3*((113/144)^(1/2)+1/4), 3*((113/144)^(1/2)-1/4) }
