Need trinomial on the left side to be a perfect square.\r
\n" ); document.write( "\n" ); document.write( "Look at the p term: -6p, if cut in half would be -3p. We would expect in the squaring process that we had -3p + -3p, suggesting constant term of -3 in the binomial. \"%28p-3%29%28p-3%29=p%5E2-6p%2B9\", so \"c=9\".
