Question

detail solution please

Answer 1

x+ y = 1

(2/3, 2/3)  = 2/3 + 2/3 = 4/3              xy = 4/9

(0, 2/3) = 0 + 2/3 = 2/3                     xy = 0

(1/3, 1/3 ) = 1/3 + 1/3 = 2/3                  xy = 2/9

(0, 1/3) = 0 + 1/3 = 1/3                       xy = 0

I couldn't find anyting. If (0, 3/3) it will work x+y -1 =  0 +3/3 -3/3 = 0 xy = 0*3/3 =0
