Question 852529: Kurt says that you can take the square root of each side of an equation. Therefore, he says (x+2)^2+(y-5)^2=36 and (x+2)+(y-5)=6 are equivalent equations. Dana says they are NOT. Who is correct? Explain your answer? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! You can take the sqrt of each side, but you have to get it right.
The sq root of (x+2)^2+(y-5)^2 is not (x+2)+(y-5)
