If `a+b+c=0` then find the values of the expression `((a^2+b^2+c^2)^2)/(a^2b^2+b^2c^2+c^2a^2)`

Find the value of the expression 2a+b-c when a=1, b=2 and c=0.

If a = 2 , b = -2 and c = 2 , then find the value of a^2b + b^2c + c^2a

If a^2+b^2+c^2+ab+bc+ca<=0 AA a, b, c in R then find the value of the determinant |[(a+b+2)^2, a^2+b^2, 1] , [1, (b+c+2)^2, b^2+c^2] , [c^2+a^2, 1, (c+a+2)^2]| : (A) abc(a^2 + b^2 +c^2) (B) 0 (C) a^3+b^3+c^3 + 3abc (D) 65

The simplified value of the expression (a+b-c)^2+2(a+b-c)(a-b+c)+(a-b+c)^2 is
