Extraneous solutions (video) Equations Khan Academy . When you square, when you multiply both sides by a variable expression, completely legitimate as long as you do it properly, but it's not always the case that the reverse is true. You could add or subtract anything from both sides of an equation, and that's always going to be.

Squaring each side: Suppose we start with the same equation , and then square both sides. This time we get , which has two solutions, 3 and -3. Again, the new equation is.
