%285a-12%29%2F%28a%5E2-8a%2B+5%29
= %285a+-+12%29%2F%28a%5E2+-+3a+-5a+%2B+15%29
= %285a+-+12%29%2F%28a%28a+-+3%29+-5%28a-+3%29%29
= %285a-+12%29%2F%28%28a+-+3%29%28a+-5%29%29

Similarly,
%283a+-+2%29%2F%28a%5E2+-+8a+%2B+15%29
= %283a+-+2%29%2F%28%28a+-+3%29%28a+-5%29%29

Then, %285a+-12%29%2F%28a%5E2+-+8a+%2B+15%29+-+%283a+-+2%29%2F%28a%5E2+-+8a+%2B+15%29
= %285a+-12%29%2F%28%28a+-3%29%28a+-+5%29%29+-+%283a+-+2%29%2F%28%28a+-+3%29%28a+-+5%29%29
= %28%285a-12%29-%283a-2%29%29%2F%28%28a-3%29%28a-5%29%29
= %285a-12-3a%2B2%29%2F%28%28a-3%29%28a-5%29%29
= %282a-10%29%2F%28%28a-3%29%28a-5%29%29
= %282%28a-5%29%29%2F%28%28a-3%29%28a-5%29%29
= 2%2F%28a-3%29
