Solution for x+2/2x^2+13x+20-x+3/2x^2+13x+20 equation: 


x in (-oo:+oo)

(2/2)*x^2+(3/2)*x^2+x+13*x-x+13*x+20+20 = 0

5/2*x^2+26*x+40 = 0

DELTA = 26^2-(5/2*4*40)

DELTA = 276

DELTA > 0

x = (276^(1/2)-26)/(2*5/2) or x = (-276^(1/2)-26)/(2*5/2)

x = (2*69^(1/2)-26)/5 or x = (-2*69^(1/2)-26)/5

x in { (-2*69^(1/2)-26)/5, (2*69^(1/2)-26)/5 }
