8a^3+c^3=2^3a^3+c^3
\n" ); document.write( "=(2a)^3+c^3
\n" ); document.write( "use following sum of cubes formula to solve:
\n" ); document.write( "x^3+y^3=(x+y)(x^2-xy+y^2)
\n" ); document.write( "For given problem:
\n" ); document.write( "x=2a
\n" ); document.write( "y=c
\n" ); document.write( "You can take it from here to solve.
