Question

if a = 252, b = 258, c= 260, then value of
a2+b2 + C2 - ab-bc-ac is?
​

Answer 1

Answer:

52

Step-by-step explanation:

Given values

a = 252

b = 258

c = 260

Given equation,

a^2 + b^2 + c^2 - ab - bc - ac

Substitute the values

(252)^2 + (258)^2 + (260)^2 - (252)(258) - (258)(260) - (260)(252)

Calculate them

63504 + 66564 + 67600 - 65016 - 67080 - 65520

By simplifying further

197668 -  197616

By subtracting we get

52

∴ The value of equation is 52
