Question

a^3-b^3)/(a-b) could you please give me the answer as well as the explanation?

Answer 1

a cube - b cube = (a-b)(a square + ab + b square )
you can now solve the problem now I think 
the answer is )(a square + ab + b square )

Answer 2

a^3-b^3 = (a-b)(a^2 + ab +b^2)  [Property]

So (a^3-b^3)/(a-b) = a^2 + ab + b^2
