25x^2 - 40xy + 16y^2\r
\n" ); document.write( "\n" ); document.write( "=(5x)^2 - 2*5x*4y + (4y)^2\r
\n" ); document.write( "\n" ); document.write( "= (5x-4y)^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "because, we know that (a-b)^2 =a^2 -2ab + b^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can also use it....\r

\n" ); document.write( "\n" ); document.write( "25x^2 - 40xy + 16y^2\r
\n" ); document.write( "\n" ); document.write( "=25x^2 - 20xy -20xy + 16y^2\r
\n" ); document.write( "\n" ); document.write( "= 5x(5x-4y)- 4y(5x-4y)\r
\n" ); document.write( "\n" ); document.write( "= (5x-4y)(5x-4y)\r
