When solved correctly, the equation \( \sqrt { - 2 x - 5 } = x + 4 \) has solutions of \( x = - 7 \) and \( x = - 3 \) . Which, if any, of the solutions are extraneous? Both \( x = - 7 \) and \( x = - 3 \) are extraneous. Only \( x = - 7 \) is extraneous. Neither solution is extraneous. Only \( x = - 3 \) is extraneous.
