What is (x+5)^3 + 8 = 0
\n" ); document.write( "Subtract 8 from both sides
\n" ); document.write( "(x+5)^3 = -8
\n" ); document.write( "Find the cube root of both sides
\n" ); document.write( "x + 5 = -2
\n" ); document.write( "x = -2 - 5
\n" ); document.write( "x = -7
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in original problem
\n" ); document.write( "(-7+5)^3 + 8 = 0
\n" ); document.write( "(-2)^3 + 8 = 0
\n" ); document.write( "-8 + 8 = 0; confirms our solution of x=-7 \n" ); document.write( "
\n" );
