Best ResponseYou've already chosen the best response.0sqrt(2x)=x4 2x=(x4)^2 2x=x^28x+16 x^28x2x+16=0 x^210x+16=0

Best ResponseYou've already chosen the best response.0if you ever have sqrts in your problem, get rid of them by getting just one sqrt on one side of the equation and square both sides to get rid of it. the process will be continued if you have more than one

Best ResponseYou've already chosen the best response.0yes always check the x's that you get whenever you raise both sides to an even power which we did to get rid of the sqrt

Best ResponseYou've already chosen the best response.1With 2 you are using the negative root.

Best ResponseYou've already chosen the best response.1So I guess it is o.k, true you will lose negative sign when squaring so try and keep track.

Best ResponseYou've already chosen the best response.0x=2 will not work since sqrt(4) does not equal 2
