Homework Help: Solving an equation with radicals

  1. Oct 13, 2011 #1
    Hello and good evening! I'm having a fair bit of difficulty with this question, any help would be appreciated.

    1. The problem statement, all variables and given/known data
    Answers are required in mixed radical form.

    2. Relevant equations
    The quadratic formula/factoring will be useful near the end of the problem.

    3. The attempt at a solution
    I squared both sides of the equation to get
    However I'm not quite sure how to proceed and whether eliminating the radical in the first step was the correct step.

    You are doing the right step but you squared the right side wrong. (x-1)^2 isn't equal to x^2+1. Try that again.

    You're right! I completely forgot it was a binomial. Thanks for your help.
