Question 77088
Write each expression in simplest form.
4r^2 – 25s^2 / 2r^2 + 3rs – 20s^2
:
{{{((4r^2 - 25s^2)) / ((2r^2 + 3rs - 20s^2))}}}
:
Note the numerator is the difference of squares: & denominator will also factor
{{{((2r+5s)(2r-5s)) / ((2r-5s)(r+4s))}}}
:
Cancel out (2r-5s)'s and you have;
{{{((2r+5s)) / ((r+4s))}}}
