1. Step-by-step explanation:

   Y2+1/3y=2

   Multiplying the equation by 3

   3y^2+y=6

   3y^2+y-6=0

   On comparing with the equation

   ax^2+bx+c=0

   a=3,b=1,c=-6

   Now

   b2-4ac=(1)^2-4X3X(-6) = 1+72=73

   X=-b+ root b2- 4ac

2. Answer:

   y= -2,1

   Step-by-step explanation:

   y²+y=2

   y²+y-2=0

   y²+2y-y-2=0

   y(y+2)-1(y+2)=0

   (y+2)(y-1)

   y= -2,1
