how would i solve this problem? (z+5)^3
\n" ); document.write( "(z+5)^3=(z+5)(z+5)(z+5)=(z+5)(z+5)^2=(z+5)(z^2+10z+25)
\n" ); document.write( "multiply by z, then multiply by 5, then combine like terms
\n" ); document.write( "=z^3+10z^2+25z+5z^2+50z+125
\n" ); document.write( "=z^3+15z^2+75z+125
\n" ); document.write( "
\n" );
