right setup
\n" ); document.write( "you just didnt use the quadratic formula?
\n" ); document.write( " $\"x%5E2+-2x+=+63\"$
\n" ); document.write( " $\"x%5E2-2x-63=0\"$
\n" ); document.write( "-9 and 7
\n" ); document.write( "-9 times 7 = -36
\n" ); document.write( "-9 plus 7 = -2
\n" ); document.write( "so:
\n" ); document.write( " $\"%28x-9%29%28x%2B7%29=0\"$
\n" ); document.write( "x=9,-7
\n" ); document.write( "two possible answers
