Solution for 10y/2y+1-8y-1/2y+1 equation: 


y in (-oo:+oo)

((10*y)/2)*y-(8*y)-((1/2)*y)+1+1 = 0

((10*y)/2)*y-8*y+(-1/2)*y+1+1 = 0

5*y^2-17/2*y+2 = 0

DELTA = (-17/2)^2-(2*4*5)

DELTA = 129/4

DELTA > 0

y = ((129/4)^(1/2)+17/2)/(2*5) or y = (17/2-(129/4)^(1/2))/(2*5)

y = ((129/4)^(1/2)+17/2)/10 or y = (17/2-(129/4)^(1/2))/10

y in { (17/2-(129/4)^(1/2))/10, ((129/4)^(1/2)+17/2)/10 }
