Solution for 3y^2-5y+2/3y^2-7y+4 equation: 


y in (-oo:+oo)

3*y^2+(2/3)*y^2-(5*y)-(7*y)+4 = 0

3*y^2+(2/3)*y^2-5*y-7*y+4 = 0

11/3*y^2-12*y+4 = 0

DELTA = (-12)^2-(11/3*4*4)

DELTA = 256/3

DELTA > 0

y = ((256/3)^(1/2)+12)/(2*11/3) or y = (12-(256/3)^(1/2))/(2*11/3)

y = 3/22*((256/3)^(1/2)+12) or y = 3/22*(12-(256/3)^(1/2))

y in { 3/22*(12-(256/3)^(1/2)), 3/22*((256/3)^(1/2)+12) }
