ANSWER...........................
given expression = a^2(a+3c)/2 + (a+c)^3/2 + c^2(3a+c)/2
                         =a^3/2+3a^2c/2+a^3/2+c^3/2+3a^2c/2+3ac^2/2+3ac^/2+c^3/2...

                         =a^3 +c^3 + 3a^2c + 3ac^2
                         =(a+c)^3................
The inevitable truth of life.....everyone in our life is going 2 hurt sooner or later......u just have 2 realise who is worth.....
