$\"y=x2%2B2x-3\"$ --> $\"y=x2%2B2x%2B1-4\"$ --> $\"y=%28x%2B1%29%5E2-4\"$
\n" ); document.write( " $\"%28x%2B1%29%5E2%3E=0\"$ --> $\"%28x%2B1%29%5E2-4%3E=-4\"$
\n" ); document.write( "So for $\"highlight%28c%3C-4%29\"$ $\"y=x2%2B2x-3%3E=-4%3Ec\"$
\n" ); document.write( "and the two equations have no point in common.
