Factor the left side:\"x%5E4%28x%2B3%29=x%2B3\", assuming x≠-3, divide both sides by\r
\n" ); document.write( "\n" ); document.write( "x+3 and get:\"x%5E4=1\"=>\"x%5E4-1=0\"=>\"%28x%5E2-1%29%28x%5E2%2B1%29=0\"=>\r
\n" ); document.write( "\n" ); document.write( "=>\"%28x-1%29%28x%2B1%29%28x%5E2%2B1%29=0\". The real solution set is: {-1, 1}.\r
