Some Direct Inequalities (TOMATO Subjective 80)

Problem: If \(a,b,c\) are positive numbers, then show that \(\frac{b^2+c^2}{b+c}+\frac{c^2+a^2}{c+a}+\frac{a^2+b^2}{a+b}\geq a+b+c\) Solution: This problem can be solved using a direct application of the Titu’s Lemma but we will instead prove the lemma first...
