Both Solutions Are Correct

x² = 4 x = −2 x = +2

A classical painting shows several nude figures falling or reaching upward, with mathematical labels overlaid: x² = 4, x = −2, and x = +2. The joke is that both positive and negative two are valid solutions, so the equation has split the figures between its two answers. It is used as a reaction to situations where multiple contradictory outcomes are simultaneously correct.
