Write each expression in simplest form.
4r^2 – 25s^2 / 2r^2 + 3rs – 20s^2
:
%28%284r%5E2+-+25s%5E2%29%29+%2F+%28%282r%5E2+%2B+3rs+-+20s%5E2%29%29
:
Note the numerator is the difference of squares: & denominator will also factor
%28%282r%2B5s%29%282r-5s%29%29+%2F+%28%282r-5s%29%28r%2B4s%29%29
:
Cancel out (2r-5s)'s and you have;
%28%282r%2B5s%29%29+%2F+%28%28r%2B4s%29%29
