This is the difference of 2 squares.
\n" ); document.write( "The general difference of squares equation is x^2-y^2=(x+y)(x-y).
\n" ); document.write( "In this case, the square root of 4m^2 is 2m and the square root of 25 is 5.
\n" ); document.write( "So 4m^2-25=(2m+5)(2m-5). \n" ); document.write( "

\n" );
