Solve. \[ x^{4}-13 x^{2}+36=0 \] If there is more than one solution, separate them with commas. \( x=\square \)

List the critical values of the related function. Then solve the inequality. \[ \frac{4 x}{11 x-2}>\frac{x}{x+7} \] The critical value(s) is/are (Simplify your answer. Type an integer or a simplified fraction. Type an exact answer, using radicals as ne as needed.)
