$\frac{19}{4}rs -\frac{8}{3}r^2+\frac{1}{4}rs +9$

The only like terms are 19/4rs and 1/4rs because they have the same variables, so: [I rearranged, to put the like terms next to each other]

$-\frac{8}{3}r^2+\frac{19}{4}rs+\frac{1}{4}rs+9$ Since the denominators are already the same, you can combine the fractions

$-\frac{8}{3}r^2+\frac{20}{4} rs+9$

$-\frac{8}{3} r^2+5rs+9$
