Solution for (6/7x^2+6x)+(1/2x^2-1/3x) equation: 


x in (-oo:+oo)

(6/7)*x^2+(1/2)*x^2+6*x-((1/3)*x) = 0

(6/7)*x^2+(1/2)*x^2+6*x+(-1/3)*x = 0

19/14*x^2+17/3*x = 0

DELTA = (17/3)^2-(0*19/14*4)

DELTA = 289/9

DELTA > 0

x = ((289/9)^(1/2)-17/3)/(19/14*2) or x = (-(289/9)^(1/2)-17/3)/(19/14*2)

x = 0 or x = -238/57

x in { -238/57, 0 }
