Substitute $\"u=x%5E2\"$ ,
\n" ); document.write( " $\"x%5E4-6x%5E2%2B5=u%5E2-6u%2B5\"$
\n" ); document.write( " $\"x%5E4-6x%5E2%2B5=%28u-5%29%28u-1%29\"$
\n" ); document.write( " $\"x%5E4-6x%5E2%2B5=%28x%5E2-5%29%28x%5E2-1%29\"$
\n" ); document.write( " $\"x%5E4-6x%5E2%2B5=%28x-sqrt%285%29%29%28x%2Bsqrt%285%29%29%28x-1%29%28x%2B1%29\"$
\n" ); document.write( "Not sure what you mean by the sum of the factors,
\n" ); document.write( " $\"x-sqrt%285%29%2Bx%2Bsqrt%285%29%2Bx-1%2Bx%2B1=4x\"$
\n" ); document.write( "or
\n" ); document.write( " $\"sqrt%285%29-sqrt%285%29%2B1-1=0\"$
\n" ); document.write( " \n" ); document.write( "
