I solve the problem step by step.Hope you understand.Thank you.
Page - 319) The given inequality is 1 1 s mnt n24041 Le fly solve the inequality step by step Now find the critical points of the inequality -18 n? m² tnt1 a? TA 1 - m²+2+1 (multiplying both side by m multiplying both side by n2+1+1=n m² tomt mention? = x2-02 I sub toast in² froom both sides => 3+1 0 → a=-1 Check possible critical points ms-t (works in original equation in

page- critical points : n=1 (makes both side equal x=0 makes lefut denominators equal to o Now we check inderavals in between critical points. (Test values in the intervals to see is they work.) 23- (Doesn't work in original inequality -13240 (works in original inequality) a 30 (Wonks in original inequally) bo the answer is -Ilnco on nyo This is the required values Of x for which the given inequality is drove.
