Solution for x=2/31/2x^2-5x+2 equation: 


x in (-oo:+oo)

x = ((2/31)/2)*x^2-(5*x)+2 // - ((2/31)/2)*x^2-(5*x)+2

x-(((2/31)/2)*x^2)+5*x-2 = 0

(-1/31)*x^2+x+5*x-2 = 0

6*x-1/31*x^2-2 = 0

DELTA = 6^2-(-2*(-1/31)*4)

DELTA = 1108/31

DELTA > 0

x = ((1108/31)^(1/2)-6)/(-1/31*2) or x = (-(1108/31)^(1/2)-6)/(-1/31*2)

x = -31/2*((1108/31)^(1/2)-6) or x = 31/2*((1108/31)^(1/2)+6)

x in { -31/2*((1108/31)^(1/2)-6), 31/2*((1108/31)^(1/2)+6) }
