x^2+kx+36 what is the value of k for which the expression is a perfect square trinomial
\n" ); document.write( "-------------------
\n" ); document.write( "It's ax^2 + bx + 36
\n" ); document.write( "-----------
\n" ); document.write( "For a perfect sq trinomial,
\n" ); document.write( "c = (b/2)^2
\n" ); document.write( "c = b^2/4
\n" ); document.write( "\"b+=+sqrt%284c%29\"
\n" ); document.write( "k = b\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
