Solve:
\n" ); document.write( " $\"x%5E2-6x%2B13+=+0\"$ ?
\n" ); document.write( "Using the quadratic formula: $\"x+=+%28-b%2B-sqrt%28b%5E-4ac%29%29%2F2a\"$ and, in this problem: a = 1, b = -6, and c = 13.
\n" ); document.write( " $\"x+=+%28-%28-6%29%2B-sqrt%28%28-6%29%5E2-4%281%29%2813%29%29%29%2F2%281%29\"$ Evaluate:
\n" ); document.write( " $\"x+=+%286%2B-sqrt%2836-52%29%29%2F2\"$
\n" ); document.write( " $\"x+=+%286%2B-sqrt%28-16%29%29%2F2\"$
\n" ); document.write( " $\"x+=+6%2F2%2Bsqrt%28-16%29%2F2\"$ or $\"x+=+6%2F2-sqrt%28-16%29%2F2\"$ and these can be simplified to:
\n" ); document.write( " $\"x+=+3%2B%284%2F2%29sqrt%28-1%29\"$ or $\"x+=+3-%284%2F2%29sqrt%28-1%29\"$
\n" ); document.write( " $\"highlight%28x+=+3%2B2i%29\"$ or $\"highlight%28x+=+3-2i%29\"$ \n" ); document.write( "
