This equation will not factor so we must use the Quadratic Formula (or complete the square):
\n" ); document.write( " $\"x+=+%28-%287%29+%2B-+sqrt%28%287%29%5E2+-+4%281%29%28-12%29%29%29%2F2%281%29\"$
\n" ); document.write( "which simplifies as follows:
\n" ); document.write( " $\"x+=+%28-%287%29+%2B-+sqrt%2849+-+4%281%29%28-12%29%29%29%2F2%281%29\"$
\n" ); document.write( " $\"x+=+%28-%287%29+%2B-+sqrt%2849+%2B+48%29%29%2F2%281%29\"$
\n" ); document.write( " $\"x+=+%28-%287%29+%2B-+sqrt%2897%29%29%2F2%281%29\"$
\n" ); document.write( " $\"x+=+%28-7+%2B-+sqrt%2897%29%29%2F2\"$
\n" ); document.write( "In long form this is:
\n" ); document.write( " $\"x+=+%28-7+%2B+sqrt%2897%29%29%2F2\"$ or $\"x+=+%28-7+-+sqrt%2897%29%29%2F2\"$ \n" ); document.write( "
