Solution for (3/5x^2+13x+8)+(2/5x^2+18x+16) equation: 


x in (-oo:+oo)

(3/5)*x^2+(2/5)*x^2+13*x+18*x+8+16 = 0

x^2+31*x+24 = 0

DELTA = 31^2-(1*4*24)

DELTA = 865

DELTA > 0

x = (865^(1/2)-31)/(1*2) or x = (-865^(1/2)-31)/(1*2)

x = (865^(1/2)-31)/2 or x = (-(865^(1/2)+31))/2

x in { (-(865^(1/2)+31))/2, (865^(1/2)-31)/2 }
