Solve:
\n" ); document.write( " $\"5x%5E2%2B2x-1+=+0\"$ Use the quadratic formula: $\"x+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a\"$
\n" ); document.write( " $\"x+=+%28-2%2B-sqrt%282%5E2-4%285%29%28-1%29%29%29%2F2%285%29\"$
\n" ); document.write( " $\"x+=+%28-2%2B-sqrt%284%2B20%29%29%2F10\"$
\n" ); document.write( " $\"x+=+%28-2%2B-sqrt%2824%29%29%2F10\"$
\n" ); document.write( " $\"x+=+%28-2%2B2sqrt%286%29%29%2F10\"$ Simplify this to: $\"x+=+%28-1%2Bsqrt%286%29%29%2F5\"$
\n" ); document.write( " $\"x+=+%28-2-2sqrt%286%29%29%2F10\"$ Simplify this to: $\"x+=+%28-1-sqrt%286%29%29%2F5\"$ \n" ); document.write( "
