How do you apply Cauchy-Schwarz to the RHS?

At first glance, it is not clear how we can apply Cauchy-Schwarz, as there are no squares that we can use. Furthermore, the RHS is not a perfect square. The power of Cauchy-Schwarz is that it is extremely versatile, and the right choice of can simplify the problem. ( a c × c + b a × a + c b × b) 2 ≤ ( a 2 c + b 2 a + c 2 b) ( c + a + b).
