I shall explain in setps
numerator = 16x^2y^2+24x^3y
take the GCD as common factor and factorise( 8 devides both so x^2 and y hence 8x^2y
8x^2y(2y+3x)
now denominaotor
= 8x^3y^2-4x^2y = 4x^2y(2xy-1)
devide to get 8x^2y(2y+3x)/(4x^2y(2xy-1)) = 2(2y+3x)/(2xy-1)

??? i dont understand how you got that. could i say 2x^y^2+3x^3y/xy^2??

Prove whether it is right or wrong
it is impossible to write
a^(n) - b^(n) = c^(2)
having natural solutions of a,b & c for n>2.
i.e. u can write
a^(2) -b^(2) =c^(2)
but u cannot write
d^(3)-f^(3)= a perfect square
or,x^(n)-v^(n) = a perfect square [sayr^(2)] when n>2 where x , v & r will have natural solution.

Everything I've ever read about carnivorous dinosaurs has been about theropods (carnosaurs, coelurosaurs etc. etc.).

Were there ever any non-theropod carnivorous dinosaur genera?

(specifically excluding non-dinosaur extinct carnivorous reptiles such as mosasaurs, dimetrodon etc etc).
