$\"%28x%5E2-3%29%28x%5E2%2B3x-4%29=0\"$
\n" ); document.write( " $\"%28x%5E2-3%29=0\"$ Set each factor equal to zero
\n" ); document.write( " $\"x=0%2B-sqrt%283%29\"$ There's one set of roots
\n" ); document.write( " $\"%28x%5E2%2B3x-4%29=0\"$
\n" ); document.write( " $\"%28x%2B4%29%28x-1%29=0\"$ Factor the right side
\n" ); document.write( " $\"x%2B4=0\"$
\n" ); document.write( " $\"x=-4\"$
\n" ); document.write( " $\"x-1=0\"$
\n" ); document.write( " $\"x=1\"$
\n" ); document.write( "So the roots are
\n" ); document.write( " $\"x=1\"$ , $\"x=-4\"$ , $\"x=sqrt%283%29\"$ and $\"x=-sqrt%283%29\"$ . Since this is a 4th degree polynomial, we have found all the roots and they are all real roots. \n" ); document.write( "
