solve (w+2)^3+88=0 where w is a real number.
\n" ); document.write( ":
\n" ); document.write( "(w+2)^3 = -88
\n" ); document.write( "Find the cube root of both sides
\n" ); document.write( "w + 2 = $\"3sqrt%28-88%29\"$
\n" ); document.write( "factor inside the radical to reveal a perfect cube, -8
\n" ); document.write( "w + 2 = $\"3sqrt%28-8%2A11%29\"$
\n" ); document.write( "extract the cube root of -8
\n" ); document.write( "w + 2 = $\"-2%2A3sqrt%2811%29\"$
\n" ); document.write( "subtract 2 from both sides
\n" ); document.write( "w = $\"-2%2A3sqrt%2811%29\"$ - 2
\n" ); document.write( " \n" ); document.write( "

\n" );
