Solve:
\n" ); document.write( "\"x%5E3%2B3x%5E2-x-3+=+0\" Factor.
\n" ); document.write( "\"%28x%5E2-1%29%28x%2B3%29+=+0\" Factor the left parentheses.
\n" ); document.write( "\"%28x%2B1%29%28x-1%29%28x%2B3%29+=+0\" Apply the zero products principle.
\n" ); document.write( "\"x%2B1+=+0\" and/or\"x-1+=+0\" and/or\"x%2B3+=+0\"
\n" ); document.write( "If \"x%2B1+=+0\" then \"x+=+-1\"
\n" ); document.write( "If \"x-1+=+0\" then \"x+=+1\"
\n" ); document.write( "If \"x%2B3+=+0\" then \"x+=+-3\"\r
\n" ); document.write( "\n" ); document.write( "The roots are:
\n" ); document.write( "x = -1
\n" ); document.write( "x = 1
\n" ); document.write( "x = -3
\n" ); document.write( "
\n" );
