Best ResponseYou've already chosen the best response.1"two positive numbers whose sum is 100" > x+y = 100 x+y = 100 y = 100x  "the sum of whose squares is a minimum" z = x^2 + y^2 z = x^2 + (100x)^2 z = x^2 + 10000  200x + x^2 z = 2x^2  200x + 10000 So you'll then want to find the vertex of 2x^2  200x + 10000
