Solution for 2x2/5+5x/6=10 equation: 


x in (-oo:+oo)

(2*x^2)/5+(5*x)/6 = 10 // - 10

(2*x^2)/5+(5*x)/6-10 = 0

2/5*x^2+5/6*x-10 = 0

DELTA = (5/6)^2-(-10*2/5*4)

DELTA = 601/36

DELTA > 0

x = ((601/36)^(1/2)-5/6)/(2/5*2) or x = (-(601/36)^(1/2)-5/6)/(2/5*2)

x = 5/4*((601/36)^(1/2)-5/6) or x = -5/4*((601/36)^(1/2)+5/6)

x in { -5/4*((601/36)^(1/2)+5/6), 5/4*((601/36)^(1/2)-5/6) }
