I need all of the steps.
I need this ASAP because this assignment is due tomorrow.
Thanks

What do you want done?? Do you want it solved for y?
If so, first square both sides, which would leave you:
(2-y)(2-y)=y+4
FOIL
4-4y+y^2=y+4
Then subtract 4 and y which would get you
y^2-5y=0
Factor out the y.
y(y-5)=0
y=0 or y=5
(2-y)(2-y)=y+4
FOIL
4-4y+y^2=y+4
Then subtract 4 and y which would get you
y^2-5y=0
Factor out the y.
y(y-5)=0
y=0 or y=5
