Using properties of determinants prove that -
(b+c)2....a2........a2
b2.....(c+a)2......b2 =2abc(a+b+c)3
c2.....c2.......(a+b)2
In this ques.. i just want to know tht after applying C1→ C1-C2, C2→ C2-C3
in this ques how can i take (a+b+c) common from C1 and C2.
After applying the properties that is
C1 = C1 - C3 and C2 = C2 - C3 , we get
Hope your doubt is cleared now.
