Fill in the Blank

A systems analyst is verifying a performance model defined by the equation r+4r+2=0\sqrt{r+4} - r + 2 = 0. During the solution process, squaring both sides leads to two candidate solutions: r=0r = 0 and r=5r = 5. Upon checking these values in the original equation, the analyst discovers that r=0r = 0 does not satisfy the formula. In mathematics, this type of invalid result is known as an ________ solution.
