I'm almost confident that I did this wrong, but i tried...

Answer:

4a-9 ÷ -19

Explanation:

(It was easier for me to put it in fractions)

(2(a-3))/((a-4)(a-5)) +
(a-1)/((3-a)(a-4)) +
(a-2)/((5-a)(a-3)) (3-a) (a-4) + (5-a) (a-3)

(2a-6)/((a-4)(a-5)) +
(a-1)/((3-a)(a-4)) +
(a-2)/((5-a)(a-3)) 3 - a · a - 4 + 5 - a · a - 3

(2a-6)/((2a-20)) +
(a-1)/((3-a)(a-4)) +
(a-2)/((5-a)(a-3)) 3 - a + 1 - a - 3

(2a-6+a-1+a-2)/((2a-20)+(3-a)(a-4)+(5-a)(a-3)) 1 - a - a

(4a-9)/(2a-20+1-2a) 1 - 2a

(4a-9)/(2a-19-2a)

(4a-9)/(-19)
