If the "v" is really a square root symbol, the possible answers make much more sense.
sqr(6x-4) - sqr(2x + 10) = 0
There are 2 terms on the left side with square roots. If the whole left side was under one square root you could square each side, but it isn't. If you add sqr(2x + 10) to both sides, then EACH side of the equation would be under one square root, and THEN you could square each side. But the first step was isolating each square root term to its own side of the equation.
