    You already know the square root of 144. At least I hope you do.

    Yes, it does, because now you have reduced it to: 12 - sqrt(40) - sqrt(10)

    That's now how you're supposed to express the solution.

    I thought for a moment 12 - sqrt(40) - sqrt(10) was one of the answers that I had the choice to take, but it was wrong.

    I* was wrong. The other choice was 12 - sqrt(10).

    Are you sure one of the answer choices wasn't 12 - 3sqrt(10)?

    Yes, there was. I should've seen that, but I forgot that sqrt(40) is just double sqrt(10) so then it's 3 times that. Thank you.
