Answer 1

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

Answer 2

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
