Best ResponseYou've already chosen the best response.0the answer is supposed to be x=0 but I don't know why

Best ResponseYou've already chosen the best response.0Move one radical to the other side of the equation and then square each side. Remember that the right side will be a binomial so you will need to FOIL it. You will get a radical in the product so you will need to isolate it and solve it the same way by squaring each side.

Best ResponseYou've already chosen the best response.0so when you move the radical over, your new equation is: √(x+4)=1+√(x+1)

Best ResponseYou've already chosen the best response.0Yup. Now square each side. FOIL the right side.

Best ResponseYou've already chosen the best response.0the left side just "pops" out as x+4?

Best ResponseYou've already chosen the best response.0yes, I'm making it overly complicated.

Best ResponseYou've already chosen the best response.0you'll get this and then combine like terms and isolate the radical again. \[x+4=x+1+2\sqrt{(x+1)} + 1\]

Best ResponseYou've already chosen the best response.0I'm afraid you lost me again.

Best ResponseYou've already chosen the best response.0This is what you get when you square both sides.

Best ResponseYou've already chosen the best response.0but then if you tried to get stuff over on the left, your x disappears...

Best ResponseYou've already chosen the best response.0It's OK because you still have one under the radical. Did you get \[2=2\sqrt{(x+1)}\]

anonymous

Best ResponseYou've already chosen the best response.0yes, then do you get 4=4(x+1)?

anonymous

Best ResponseYou've already chosen the best response.0I would've divided both sides by 2 first, but you'll still get x=0 in the end.

Best ResponseYou've already chosen the best response.0alright, let me try it that way then...I did not get to 0....

Best ResponseYou've already chosen the best response.0YES!! Got it! Thank you so much for the step by step!!

Best ResponseYou've already chosen the best response.0After dividing both sides by 2, you'll get \[1=\sqrt{(x+1)}\]
