PLEASE HELP FAN AND MEDAL
Arnie says that you can take the square root of each side of an equation. Therefore, he says
that ( x + 2)2 + ( y – 5)2 = 64 and ( x + 2) + ( y – 5) = 8 are equivalent equations. Frankie says the equations are not equivalent. Who is right? Explain your answer.

-I don't think you can take the square of both sides of the equation, but I don't understand how to find the answer??

HI!!

misty1212 · Answer

you can take the square root of both sides, but you would get $$\sqrt{(x+2)^2+(y-5)^2}=8$$

misty1212 · Answer

and $$\sqrt{(x+2)^2+(y-5)^2}$$is not the same thing as $$(x+2)+(y-5)$$ at all

okay, so Frankie is right? @misty1212 (sorry i only saw this now opensutdy didnt alert me!)
