Quick Math: Solve Square Numbers End with Five

For example:
152 = 225
252 = 625
352 = 1225
452 = 2025
552 = 3025

.....

If the first digit is X and the second digit is 5, then the last 2 digits of the answer will be 25, and the preceding digits will be X × (X + 1).

For Example:
652 = _ _ 2 5

Then, the first digit is 6. So, 6 × (6 + 1) = 6 × 7 = 42.
Finally, the answer is 4225.

652 = 4 2 2 5

852 = ____
952 = ____
