Provide an appropriate response.What value of x will make the following equation true? Explain your answer. 
What will be an ideal response?
x = 
. Since neither square root can have a value less than 0, both must equal 0 for their sum to be 0. For a square root to equal 0, its radicand must also equal 0. Thus, 4x - 2 = -8x + 4 = 0, which yields the solution x = 
. (Explanations will vary.)
