I have the equation (x+k)^2 = -d (7) I want to get (x+k) = sqrt(-d) by inputting sqrt(lhs((7))) = sqrt(rhs((7))) but I run into that old problem of sqrt(v^2) = sqrt(v^2) I realize you can use 'assuming' but its awkward and messy in this case. Perhaps the best way to present this question is to ask "What's the easiest way you can get from (7) to (x+k) = sqrt(-d) (8)
