Isolate the square root term:



Square both sides:



Squaring a square root takes away the square root



Write the left sides as 



Use FOIL



Subtract  from both sides:



Isolate the term that contains y, which is -2xy.
Since it's negative on the left, we isolate it
on the right:



Divide both sides by 2x
