Never true. Using the foil method (First, Outer, Inner, Last)
\n" ); document.write( "F=a*a
\n" ); document.write( "O=a*b
\n" ); document.write( "I=a*b
\n" ); document.write( "L=b*b
\n" ); document.write( "This looks like this: a^2+ab+ab+b^2
\n" ); document.write( "Combine like terms:a^2+2ab+b^2\r
\n" ); document.write( "\n" ); document.write( "What your friend is probably talking about is called a perfect square trinomial which (a+b)^2=a^2+2ab+b^2. \n" ); document.write( "

\n" );
