\[2\sqrt{x-5}=2\]

I know my first step is to subtract 2 from both sides of the equation which gives me... \[\sqrt{x-5}=0\] Then I subtract 5 from both sides and I'm left with... \[\sqrt{x}=5\] Is there another step after that?

If the 2 was being `added` to the root, then yes, you would `subtract it from both sides to undo the addition.

  • zepdrix
But in this case, it looks like the 2 is `multiplying` the root, yes?
zepdrix
  • zepdrix
So how do we undo multiplication? :)

We divide :D
zepdrix
  • zepdrix
Good, yes :) Do that. It should give you something a little different than 0 on the right side.

Okay, so now I got 1 instead of 0. @zepdrix

\[\large\rm \sqrt{x-5}=1\]Cool.

Then I would add 5 and get \[\sqrt{x}=6\] @zepdrix
zepdrix
  • zepdrix
Wooops! The subtraction is `inside` of the root. We can't do that operation yet. We need to deal with the root first.

  • zepdrix
What's the inverse of `square root`? How do we undo that? :o
airyana1114
  • airyana1114
Okay so square both sides of the equation? It would still be 1 correct?
zepdrix
  • zepdrix
\[\large\rm \left(\sqrt{x-5}\right)^2=1^2\]On the left, the operations undo one another, good. On the right, 1^2 = 1? Sounds good!\[\large\rm x-5=1\]

  • airyana1114
Okay, then I would add 5 to both sides of the equation correct? @zepdrix
