the expression simplifies to
(x^{3}-x^{2})^{3}- (x^{2}+1)^{3} = 27
which has no integral solns.
$\textbf{find no. of Integral solution of the equation}\\\\ $\mathbf{x^6 + 3x^4 + 3x^2 + 28 = x^9 - 3x^8 + 3x^7 - x^6}$
the expression simplifies to
(x^{3}-x^{2})^{3}- (x^{2}+1)^{3} = 27
which has no integral solns.
