(a+b+c)3 - a3-b3-c3 = [(a+b)+c]3 – a3-b3-c3

= (a+b)3+c3+3c(a+b)(a+b+c)-a3-b3-c3

= a3+b3+3ab(a+b)+c3+3c(a+b)(a+b+c)-a3-b3-c3

= a3+b3+c3+3ab(a+b)+3c(a+b)(a+b+c)-a3-b3-c3

= 3ab(a+b)+3c(a+b)(a+b+c) 3(a+b)[ab+c(a+b+c)]

= 3(a+b)[ab+ac+bc+c2] 3(a+b)[a(b+c)+c(b+c)]

= 3(a+b)(b+c)(c+a)

  1. In {tex}\triangle{/tex}ABC and {tex}\triangle{/tex}BAC
    AD = BC [Given]
    {tex} \angle {/tex}DAB = {tex} \angle {/tex}CBA [Given]
    AB = AB [Common]
    {tex}\therefore \triangle ABD \cong \triangle BAC{/tex} [By SAS congruency]
  2. Since
    ΔABD≅ΔBAC
    {tex}\therefore {/tex} BD=AC[By C.P.C.T.]
  3. Since 
    ΔABD≅ΔBAC{tex}\triangle \mathrm{ABD} \cong \triangle \mathrm{BAC}{/tex}
    {tex}\therefore{/tex}{tex} \angle {/tex}ABD = {tex} \angle {/tex}BAC [By C.P.C.T.]
