If a^(2)+b^(2)+c^(2)-ab-bc-ca=0backslash then |a:b:c is 1:1:2 b.1:1:1 c.1:2:1 d.2:1:1

If a^(2)+b^(2)+c^(2)-ab-bc-ca=0, then a+b=c( b) b+c=ac+a=b(d)a=b=c

If a^(2) +b^(2) +c^(2) = ab + bc + ca then (a+b)/(c ) + (b+c)/(a) + (c+a)/(b) =?

In triangle ABC, if a^(2) + b^(2) +c^(2) -bc -ca -ab=0, then the value of sin ^(2)A+ sin ^(2)B+sin ^(2)C is -

If a^(2) +b^(2) +c^(2) = ab + bc + ca then (c )/(a+b) + (b)/(a +c)+ (c )/(a+b) = ?

In triangle ABC, range of (a^(2)+b^(2)+c^(2))/(ab+bc+ca) is (a,b,c are sides of triangle)

Verify that (a +b + c) (a ^(2) + b ^(2) + c ^(2) - ab - bc - ca) = a ^(3) + b ^(3) + c ^(3)- 3 abc

If a=BC,b=CA,C=AB are sides of /_ABC, such that a^(2)+b^(2)+c^(2)-6a-8b-10c+50=0 Then circum diameter of /_ABC is

If a+b+c=4 and a^(2)+b^(2)+c^(2)+3(ab+bc+ac)=21 where a, b, c in R then ab+bc+ca=

If abc=8;a,b,c in R^(+) then the minimum value of a^(2)+b^(2)+c^(2)+ab+bc+ca is equal to
