x=[tex] (15,72+325-14,6)^{2} [/tex]
x=[tex] (326,12)^{2} [/tex]

y=(250+2000)×0,25
y=2250×0,25
y=562,5

x = (15,72+325-14,6)^2
x = (340,72-14,6)^2
x = (326,12)^2

y = (2,5 * 100 + 2000) * 0,25 
y = (250+2000) * 0.25
y = 2250 * 0,25
y = 562,5
x+y = 106354,2544 + 562,5 = 106916,7544
x-y = 106354,2544 - 562,5 = 105791,7544
