Answer 2

⇒$QUESTION$

Find the two positive numbers whose sum is 15 so that the sum of their squares is minimum.

⇒$ANSWER$

⇒a+b=15

⇒f(a,b)=$a^{2}$+$B^{2}$ is minimum

⇒f(a)=$A^{2}$+(15−a$)^{2}$

⇒a=  15/12(in fraction) ,b= 15/12(in fraction)

⇒So a=  15/2   15/2 are two numbers for which f(a,b)= $A^{2}$+$B^{2}$  is  minimum
