Determine if the trinomial is a perfect square. If so, factor the trinomial. (You may have to take out a common factor first.)
\n" ); document.write( " m^2 + 18mn + 81n^2
\n" ); document.write( "--------
\n" ); document.write( "m^2 is a perfect square with square root \"m\"
\n" ); document.write( "81n^2 is a perfect square with square root \"9n\"
\n" ); document.write( "18mn is twice the product of m and 9n : 2*m*9n=18mn
\n" ); document.write( "--------------
\n" ); document.write( "The three conditions for the trinomial to be a perfect square are met.
\n" ); document.write( "-------------
\n" ); document.write( "The factors are (m+9n)(m+9n)
\n" ); document.write( "===============
