The easyest way for this 2 network summary is to take the bit format
remember :
1) IPv6 is represented in Hex
2) each part contain 16 bit
So you have here contigues 3 parts so you have 3x16 = 48
now take the 4th part and convert it to bin
12
0000 0000 0001 0010
25
0000 0000 0010 0101
now you can see very clear how many bit you can take to the summary, 10 bit
now take the first 48 bits + the 10 from your summary and you got a /58
Realy not very hard just a lot of 0 and 1.
