Our numerator is a difference of two perfect squares. So we can factor it as 2x

plus 5y times 2x minus 5y. This denominator isn't identical to one of our

factors, but it is an opposite polynomial for this factor. We can see that the

2xs are opposite in sign and the 5ys are also opposite in sign. So these two

factors simplify to be negative 1 and were left with negative 1. Times 2x plus

5y. We can distribute our negative 1 to get our answer, negative 2x minus 5y.

Fantastic work if you got that expression.
