1. The problem statement, all variables and given/known data Use the quadratic formula to solve the equation for (a) x in terms of y and (b) y in terms of x. 2. Relevant equations 4x^2 - 4xy + 1 - y^2 = 0 3. The attempt at a solution I am not really sure where to start at all. If I could just figure out the values for a, b, and c of the quadratic formula then the rest would be simple (for me). Do you take the values from the current equation like this? a = 4, b = -4y, c = 1 - y^2 I feel as if I am over analyzing this problem. If anyone could point me to a start that would be greatly appreciated. There are no examples from my textbook that pertain to this exact type of problem.
