\n" ); document.write( "You repeat the method on the second.
\n" ); document.write( "y=x^2+dx+49
\n" ); document.write( "Take the x-coefficient, halve it, square it and add and subtract it to the right hand side.
\n" ); document.write( " $\"%28d%2F2%29%5E2=d%5E2%2F4\"$
\n" ); document.write( " $\"y=x%5E2%2Bdx%2Bd%5E2%2F4%2B49-d%5E2%2F4\"$
\n" ); document.write( " $\"y=%28x%2Bd%2F2%29%5E2%2B%28196%2F4%29-d%5E2%2F4\"$
\n" ); document.write( " $\"y=%28x%2Bd%2F2%29%5E2%2B%28%28196-d%5E2%29%29%2F4\"$
