Solution for 3y+2/4y^2-4y-24+5/4y^2-16y+12 equation: 


y in (-oo:+oo)

(2/4)*y^2+(5/4)*y^2+3*y-(4*y)-(16*y)-24+12 = 0

(2/4)*y^2+(5/4)*y^2+3*y-4*y-16*y-24+12 = 0

7/4*y^2-17*y-12 = 0

DELTA = (-17)^2-(-12*7/4*4)

DELTA = 373

DELTA > 0

y = (373^(1/2)+17)/(7/4*2) or y = (17-373^(1/2))/(7/4*2)

y = 2/7*(373^(1/2)+17) or y = 2/7*(17-373^(1/2))

y in { 2/7*(17-373^(1/2)), 2/7*(373^(1/2)+17) }
