To solve for $x$, we can factor the quadratic expression. The expression factors as $(x + 5)(x - 3) = 0$. For the product of two terms to equal zero, at least one of the terms must equal zero. Therefore, either $x + 5 = 0$, or $x - 3 = 0$. Solving for $x$ in each case gives us $x = -5$ or $x = 3$. Since neither of these solutions is listed as a choice, the correct answer is the only other option, $x = -3$ or $x = 5$.
