Write each expression in simplest form.
\n" ); document.write( "4r^2 – 25s^2 / 2r^2 + 3rs – 20s^2
\n" ); document.write( ":
\n" ); document.write( " $\"%28%284r%5E2+-+25s%5E2%29%29+%2F+%28%282r%5E2+%2B+3rs+-+20s%5E2%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "Note the numerator is the difference of squares: & denominator will also factor
